I have had nothing but positive results from Key's Block & Repair Services. Jason & Jonathon are knowledgeable, professional & exemplary when servicing and/or repairing any of my diesel semi-truck cylinder head(s). They treat everyone with honesty & respect!!

If you need your cyclinder heads done I highly recommend jason at key block and repair in greensboro nc. He did excellent work. We had to get our cyclinder heads done on my dad's 1989 ford ranger and he did a excellent job resurfacing them and repairing my cyclinder heads. He didn't take long to get them done and it was done right the first time. Give jason a call to get your engine back running.

Hi Everyone This was my first time using Keys block & repair Co and I never meet the Owners Jason and his Brother in my life.. So the reason I gave 5 stars is number one HONESTY and they did an excellent job on my 2007 Suzuki forenza engine head, and I mean an Excellent job.. So if you have a Large head, Small head or Medium size head it's not a problem for them and you will be 100% Satisfied..Jason is also a very nice person who cares and who makes sure you are getting only what you need done and not charging you for what you don't need like those other guys do...Jason treats you like Family even if he don't know you and I really Appreciated that and they prices are very fair and the best price around...You will not be disappointed!!!!
