American Heritage Performance

I picked up my Z06 from Kohle at AHP yesterday. I had the stage 4 head and cam package done by him to the car. Kohle and his approach to business is by far very professional and ethical it what he does. He is extremely knowledgeable about his work and has a passion for his work. I would highly recommend his services to everyone.
Thank you Kohle for a job well done. The Z06 runs fantastic now!

If you are an LS engine /​Corvette person, tired of the dealer and just poor customer service for your LS powered vehicle then Kohle and Edwin are the guys to see. I found AHP via Corvette Forum and spoke with the owner Kohle about what I needed done. He gives you what you need and want for a fair price and quality workmanship. Unlike the dealer who will try and sell you everything you don’t need and nothing you do. Thanks to AHP I have a place to take my Vette and know I will be treated with respect and fairness. AHP also has an outstanding performance improving capabilities. Thanks Again guys, see you again.

I went to American Heritage Performance when a friend referred me. Iam very impressed with the knowledge and level of service the Guys perform here its been over a week since my service was completed and my Vette is running well i will definitely return in the near future for maintenance and performance upgrades. Thanks again Kohle.

Kohle is the man to go to with your corvette!!! I needed my transmission fixed and he took it out and had his trans guy do a rebuild for me. My car had been sitting for a year because of a bad divorce but it’s now back on the road and running great. This is my shop for the corvette I won’t let anyone else do work on it from now on. Prices are great and he specializes on corvettes so knows them inside and out. Thanks to all below me that posted reviews because that helped me decide to go to AHP.

I have seen every generation of Corvette in this shop within the last few times I have been there. Kohle is definitely the man you want to work on your Corvette or any chevy motor for that matter. He did some work to my 2009 Corvette and was honest about everything to the last detail. I definitely recommend the guy!

They put in the cam for my 2001 c5 coupe. I’m asking a lot of question but he can answer them all
He knows what he’s doing with the engine. price is very reasonable. I will always go back to them

I live in Washington State and needed my LS7 heads repaired for my 2008 Corvette Z06. I researched a few shops and came to the conclusion that it would be best for me to send my heads to American Heritage Performance for the repairs. All of my questions were answered and I even had long distance support from the shop, they were quick to respond to re-​assembly questions I had while completing the work on my car.
I asked Kohle for some recommendations on improving the horsepower on my car and he recommended head porting, a cam package, headers and a cold air intake to suit what I wanted from my car.
I am extremely happy with the quality of the repairs, the new cam and supporting modifications really increased the horsepower on my Z06. Just what I was looking for.
I highly recommend American Heritage Performance, they are a honest and helpful shop, even for the do-​it-​yourself mechanics out there.

Kohle with American Heritage Performance is the real deal and as good as it gets when it comes to quality work product, customer service, and integrity. I took my Z06 into his shop to get the valve guides redone. Kohle quoted me a fair price and had the car back in my possession in 2 weeks. Considering how many cars he is working on, I was impressed that he was able to get me my car back in that time frame. A big plus was the fact that he took the time to wash my car before returning it back to me!
After driving my car for a couple of days, I noticed a slightly rough idle and a weird ticking noise coming from the engine bay. I figured it was the new heads working themselves into place but after some time I got a check engine light. I contacted Kohle and explained the issue and he was absolutely fantastic about getting everything taken care of.
Out of precaution, he asked me to have the car towed in, in the morning. The tow truck company he recommended did an excellent job loading and unloading my car. In addition, he covered all towing costs and even offered to pay for a taxi to take me to work — all the way to Santa Monica from his shop (easily $ 80-​$ 100).
After a few hours, Kohle called me to let me know that my car was ready to be picked up. As I figured, it was a small little issue with a spark plug wire that had come loose. I picked up the car and drove it home without any issues. It is still running great and am very glad to have come across someone as honest and serious about «getting it right» as Kohle.
It’s extremely rare to find a businessman like Kohle who not only cares deeply about his craft, but is also very dedicated to making sure his customers are very well taken care of. As long as I’m in the Southbay, I won’t take my Z06 to anyone but Kohle.
Thank you sir!

I have high standards and expectations, and right from the start Kohle and Edwin at AHP impressed me with their work ethic, honesty and overall need for perfection and high standards. Their integrity was validated with a few jobs I had Kohle do and he was honest and saved me money when I asked him to perform a job that was already done when he simply could have taken my money and I wouldn’t have known. I highly recommend this shop for its quality, knowledge and overall A+ customer satisfaction and relations.
He answers calls, texts, on the weekend, at night, and always made sure I was taken care of. No other shop will touch my C6Z06 while Im in the SoCal area. Period.

Amazing customer service, very honest, and very professional. Kholey the owner and his employee Edwin is very experienced. I also got my interior consoles painted and it came out beautiful. They fixed the issue with my corvette what dealer couldn’t find and had no idea what the issue was. This shop will be the only shop I will be coming to for my corvette. They know top to bottom about corvettes and LS motors. 5 star because this shop deserves more than 5 stars. I would definitely recommend this place to everyone.

I can’t say enough about the excellence of Kohle Heimlich and American Heritage Performance. About a year ago, I was debating selling my 2005 CTS-​V, and instead I opted to try to mod it a bit to get a bump in HP. Kohler has been patient with my questions, offered excellent options, and upon request offered advice on future service. Since my first visit to Kohle’s shop, my upgrades include Kooks headers, high-​flow cats, K&N cold air intake, a LS7 clutch kit, UUC short shifter, ported and polished intake manifold and throttle body, a new cam with all the trimmings, and a killer tune. Stock this car makes about 325RWHP… with Kohle’s help, it’s turning about 425 right now and it is FUN TO DRIVE.
His work is top notch, his advice spot on, his prices are reasonable, and most important to me, he demonstrates the utmost integrity. He stands by his work, and as long as i’m hot-​rodding my V, it’ll be with Kohle.
If you’re looking for any work on an LS engine, Vette, V, etc… go talk to Kohle. you will not regret it!

Took my 2008 Z06 in to American Heritage Performance to perform the wiggle test. The owner, Kohle introduced himself. Kohle performed the wiggle test and found many of my valves were out of spec. Kohle went through my car with a fine tooth comb. He is very professional, courteous, and knowledgeable. He took great care in protecting my car while it was being worked on.
American Heritage Performance prices are reasonable and I would not hesitate to recommend them for your corvette service, repairs and mods!

This shop is top notch! Took my Z06 for head rebuild. Kohle the owner, took good care of my car. Send me pictures and update through email. Answers all my questions. Great communication. I’m very impress on the level of service. Price and work quality is good. Will come back to do business again!

Great to have a qualified and professional shop so close to Hermosa and the rest of the Southbay. Kohle has a tremendous amount of LSx knowledge and is great with both phone and email communication. From my experience communication is where a lot of shops drop the ball.
I’ll be working on a custom LS restomod project soon and wouldn’t go anywhere else work.
Stop by and talk to them and you’ll see the difference; whether you know a lot about cars or not they will make you feel comfortable and informed.

American Heritage Performance is the best shop I have ever been to!
After taking my car several places, including the dealer… looking into knowledge, turn around time, and cost. American Heritage was the best by far!
I took my Corvette Z06 in for a engine top end re-​build and they did a great and very quick.
Great Service, Fair Pricing, and Great workmanship!
Kohle the owner was very knowledgable, and kept me in the loop in the entire process and answered all my questions and get me genuine advice.
My Corvette will not go anywhere else from now on!

Update from my previous review:
Currently having Kohle finish my 1970 Porsche 914 with Chevrolet 350 swap. Keep in mind this is a custom project so that bumps and hurdles are to be expected but he has again delivered in terms of quality work. The set up looks very professional and Kohle takes time to think things through which shows in his work.
