Just heard back from the machine shop that is installing my valve guides and they said all 8 of my intake valves were bent and 5 of my exhaust valves were bent. They have had the cylinder head for almost 4 weeks now and im starting to get impatient. Has anybody every used stock replacement valves from autozone or pepboys. Im not sure if its the best idea since its going to be a turbo motor pushing 400hp or so. I know supertech and ferrea are the go-to’s for valve replacements, but i just wanted to hear if anybody has experience with the autoparts store stuff

 

If your modifying your engine and have it this far apart then it would be a good idea to install a valve made of materials, designed to take the increased cylinder temperatures from turbocharging. You can get an either valvetrain upgrade kit from supertech now that has everything you need.
