Dover Cylinder Head Service, Inc.

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.

They are really fast and professional! I fix several cylinder heads with them. Never had the issues.

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.

If you're only getting parts cleaned, prepare for disappointment. Waste of a 2hr drive, uncleaned parts, damaged block and a weeks worth of time. Completely unacceptable work! Edit: The parts were never washed. Cylinder walls were left completely dry to flash rust. Duct tape still completely bonded to intake and exhaust ports. Mineral spirits spilling into the trunk as I placed them back inside. If they needed to be media blasted, then why was it never suggested to have done to meet your customers expectations? You run the machine shop, not me. You know what 'clean' is, so that's too much trouble to even offer a simple explaination? Obviously a complete lack of communicationcare because you can't make money off of machine time by just washing. Blatantly damaging parts, disregarded while handling them. As someone who respects a company that's been around for so long, these people are still making entry level excuses while producing work that's worse than it started off to be.

BUYER BEWARE!!! THE WORST EXPERIENCE WITH A PURCHASE I'VE EVER HAD!! From the front desk woman to the owner, all of them are rude! When I had issues with the head from them they told me that if I get a 2nd opinion on whether the head they sold me is good or not then they would not honor the warranty. If you have issues and they don't find themselves at fault then you get nothing! These people are unprofessional, rude, and do not deserve your business!!! Save your money!!

I have had many different cylinder heads serviced here - resurfacing, valve guides, seals, you name it. They have always been courteous, well-priced, and provided excellent work and turnaround times. I will continue to use them for any of my cylinder head needs.
