A tip of the Hat to all of the cylinder head folks, it’s not easy just to get the installed height correct, past Tech, and run hard all the way to the Finnish line. The real good cylinder head people are a bargain.

FYI, avoid +.050 locks if you can, if not use 10° locks & retainers.
Reason is locks only clamp on the valve stem below the groove, the ID of the lock is larger above the groove.
