Dover Cylinder Head Service, Inc.

"I have 2004 suburban Dover cylinder sold me cylinder heads, lifters,push rods and a Apex gasket set everything worked and fitted beautifully HIGHLY RECOMMEND"

"I had them repair a broken off spark plug in my Cylinder Head. They were fast and drilled out the broken part and repaired it with a thread insert. Service was great and they did a good job."

"Took them my sports bike cylinder head just wanting it cleaned Chris Dover explained he could media blast it and cut new valve seats and set the clearances after being explained that I decided to go ahead and let him do the work. I had everything apart and labeled took them 3.5 weeks to get the cylinder head done came back to pick it up . Came into the shop with a assembled cylinder head and exhaust ports still caked with carbon I do believe they just cleaned the valves and reassembled the cylinder head was not media blasted. I could have reassembled the head myself complete waste of money and nothing but disappointed with this shop . Was my first and definitely will be the last time I let them do anything . Take your money and run all these 1 star reviews of them not cleaning heads and causing damage because they weren't assembled right are facts. I'm nervous now that the cylinder head will ruin my fresh built motorcycle but we will see when I start it up . Edit: Dover replied below he said he apologized for not cleaning the head and it would take them another week he's being honest that's what's he said!! After 3.5 weeks lol how can you be a machine shop and not send out a clean cylinder head when that's what you specialize in and was talked about before starting on the job.... as far as the discounted price I would have paid in full whatever price if the work was done that was discussed absolute last time they get my money."

"Fast, excellent, quality machine work on my original date coded 1967 SS Camaro heads! Thanks Chris!"

"I installed a cylinder head that was supposedly refreshed by Dover about two minutes after starting the car, the engine seized after having it taken apart by a shop, they concluded that the head was machined incorrectly and the cam cams ate through the journals and seized. Also, the front timing cover had to be a machine to fit since so much material had taken off. It would no longer form a proper seal. Do not recommend the shop. Also, if you leave a review, they’ll just badmouth you in the comments as an added bonus, they will block your number and make it impossible to get in touch. Thank you very much Chris Dover absolutely do not hand them your money and run away. There is a reason they are the only shop in the area with a short lead time on service."
