John, thank you and your staff for the wonderful job you did on my 6.0 cylinder heads. My mechanic thought they looked absolutely wonderful. We're still working on the tunes. The truck runs wonderfully; it makes lots of power. I'm glad that I chose you guys to do my work. Just a little information: here in Virginia, we have had temperatures this winter of -8 degrees and, within 24 hours, 60 degrees. Wow, those cylinder heads will take that. Hopefully they'll stay there for a long time. Any work that I need in the future will definitely come to you. The shipping charges are a small price to pay for such quality work.

You Know Your Stuff

John, I have to say I have talked to a lot of people in regards to this and you have been the most helpful so far. I can tell by talking to you that you know your stuff. Thanks so much.

Knowledge, honesty and workmanship is what describes John

I met John after looking high and low for someone that could honestly handle the rebuild of my vintage 327 Chevy engine. After speaking to several ‘shops’ in the area I was very discouraged because of the lack of professionalism and the wide range of pricing. My experience with John changed all of that though. He is extremely knowledgeable about all engines and their repair. He was especially knowledgeable about my engine and guided me through what was worth spending money on and what was not. In the end, my job was done on time and within our agreed to budget. Knowledge, honesty and workmanship is what describes John. I would have no hesitation referring anyone to him.

Hey John and David, I just wanted to update you both and say thanks again for the work and help you did for me. The car has been running like a champ for the last 2000 miles and I couldnt be happier. I’m sure it will go for another 150,000 (you better belive ill be changing that timing belt…) I will recommend you to any and everyone that I encounter that would need that kind of work. From a very happy customer. Thank you, Kevin Callaghy

The heads arrived here in great shape and they are beautiful. It’s hard for me to even find some of the fixes you did. That is, I cannot see some of them, period. Thank you for polishing the heads, also. I know that polishing them is a time-consuming and expensive additional operation. They looked very nice when they got here. I have the idea that you have more time and attention invested in these than the price you put on them shows, and they certainly look like it. I am very grateful that you took this project on. Thank you very much.

I delivered my new/re-manufactured head to my mechanic and he was impressed as was I. I just want to tell you that you are one of the most awesome people I have ever run into on this earth. I read your “Our Promise” to my wife this morning as she prepared to go in to her job at AR Children’s Hospital as a nurse manager. She was impressed too. If I get to come back to the Orlando area again in the future, I hope to get to meet you personally and shake your hand. Thanks a lot for your work ethic. Yours truly, BW

Just wanted to tell you that the aluminum heads for my 1940 Lincoln V-12 that you fixed are working flawlessly. You saved a beautiful piece of automotive history. The car won some awards because of it, woot, woot! I entered it in three shows, and it won something in all of them, from “Best Ford Motor Product” to “Best In Show,” thanks to you. Tom

You recently did a “bulletproofing” for me on my 6.0 powerstroke heads. I wanted to thank you for an excellent job. This motor runs so smooth its unbelievable. At idle there is absolutely zero vibration, like it isn’t even running. It is also noticeably quieter. Again, I appreciate your attention to detail to provide a QUALITY product. Worth every penny.

John, I just wanted to let you know how pleased I am with the work you and David did on my Dodge 4.7 heads. Your work was excellent! I put it all back together Saturday. I used the copper coat spray and cleaned the block surface really well so hopefully all will be good in the future. Maybe I’ll get another 145k out of it. I enclosed a pic. My friend said “Dodge gives you room to stand up in front of the engine because they know you’ll be working on it all the time!” lol I really appreciate the great customer service. Thanks again, Scott

Hello John, My cylinder Heads arrived this morning in absolutely immaculate condition. From the minute I called you to explain my problem, then to the purchase of second hand Cylinder Heads that I sent you, to the work you carried out on it and to the delivery from Orlando to West Yorkshire it took a staggering 3 weeks !! My friend Jim in West Yorkshire told me this morning on the phone that the work you carried out on the cylinder heads was of the highest quality with new valves added to it and that the Packaging was also very Good so the Heads were well protected. I would like to thank you for your help John. You are one of the last real genuine men who really care for their customers. I will leave a review on your website and I will recommend you to my friends and fellow Jeepers over here. Thank you and Merry Christmas to you and your Family. Kind regards, Chris

Just wanted to say thank you for the excellent work done on my heads. The truck runs great. Also merry Christmas to you and yours. Here’s a pic of the truck upstate at our hunting spot.  Nice break in run. John Zielinski

I just wanted to say thanks again for the work you did on my 6.4 cylinder heads. It took a long time to get this engine together. I found many flaws in this engine . The crank was twisted, 3 cracked pistons, front cover cavitation although common shouldn’t be happening. I want to send some pictures of the build and let you know what’s in this build in case anyone else asks what works. Its got pistons bought directly from international that do not have the stress risers in the bowl area. The crank I found was twisted,  so new crank and balanced to 6 grams . Original rods .all magnafluxed. Colt billet stage 2 camshaft. New block, front cover and 2 batmowheel billet compressor wheels with new turbos. A fluidampr crank damper and a lot of time!!!  But it runs so smooth and just wants to rev, past 2500 to 4500 it just pulls with 50 psi boost through a banks intercooler. It’s just a fun truck to drive. Thanks. John Zielinski

I just wanted to thank you for the exceptional service I received at your shop. You guys were very informative, finished my heads right on schedule and even taught me a few “tricks of the trade”. I will use you for all of my cylinder head needs and will also refer your shop to all of my friends.
