Engine Laboratory

Kelly is a very honest man. My son brought him cylinder heads to have them professionally cleaned not long after he dropped them off Kelly called and left a message on my voicemail to call him back. I called him back the next day he said they were cracked and didn't do anything with them. He said we need to pick them up when we can. He could've lied, cleaned them up and charged me, I wouldn't have known the difference.

He also could've lied and said he'll dispose of them and sell them to someone else. I can't thank him enough for his honesty. Honesty is worth more to me then the professional work. My son will be doing business with him in the near future on his small engines.

I needed to have a set of 3800 L36 heads setup with oversized valves. Took the job to National Cylinder Heads, and very happy that I did.

Quick, efficient, and perfect. Dropped off my brother's mitsu 2.4 head off for a resurface. They knocked it out and was ready for me next day. I drove from Homosassa, an hour through the tolls, and it was well worth it. Just finished the job today and head sealed to the mls headgasket without any issues. Thanks again!

Called and asked if they could install new valve seats, was told "that usually shouldn't be needed" and "we wouldn't do that here". Seems like someone is not knowledgeable about their services OR their name is very misleading.

Kelly is the best machinists I have ever dealt with and his work proves it been using National Clyinder Head for about 20years

Kelly and his staff are awesome. Took time to talk with me and even took me back to see the 383 heads in process. I was impressed with there kindness. Felt like family. My grandfather's 66 charger is back on the he street. Ty. 110 over gandy bridge.

I was referred there by my friend/mechanic in 2014. They did a great rebuild job on the heads of my 94 legend coupe, which I still drive. 2 years later they did it again on my 95 t100. Good work & affordable prices especially if you would really like to keep the vehicle. I'm happy these skilled craftsman are still around & easy on the finances.

I have cylinder heads rebuilt here. Friendly, knowledgeable and cant beat the price. Ive had a dozen sets of heads done and the work is always top notch. I've never had any performance work done here but no complaints on any street machines.

I have used NCH over the years. I am no pro mechanic but know I trust this company every time I have a project I want done right. Over the past 20 years I have used them 5 times. Fast turn around, expert knowledge and advice, friendly, and trust worthy. I am starting more projects and will be using NCH as part of every rebuild.
