It is a brand new head cast to oem specs thickness wise. No shaving done. With upgraded springs retainers new oem viton seals, etc. It is called the lce street performer which is a cast aluminum cylinder head with upgraded seals and hardened seats, valve springs for the higher lift cam. I just needed to know if the valve to piston clearance would be okay, and no my motor is timed good just replacing a head and cam and rockers.
