fully built gsr head complete crower valvetrain on boost? opinions
ok i have a fully built gsr (p72) head has:
crower stage 2 402's
crower ti retainers
crower dual valve springs
crower premium 1mmover stainless steel valves (intake&exhaust)
mild port work in all the right places
skunk2 cam gears
my question is i am wanting to use this head on my boosted built block with low compression pistons...... my question is will this head setup cause any problems with boost? like camshaft lift or duration or anything like that, i just dont want to burn valves or cause any damage to the head.

You need to have the engine clayed to check for piston to valve clearance, has the head been milled at all?

Its an issue with oversize valves and high lift cams, better be safe than sorry, especially if you have adjustable cam gears and start messing with them. I have .5mm Oversize with a head that has been milled 2x and pistons out of the bore w/ Stock GSR cams.... I DID NOT check so I am terrified to adjust my cam gears or switch to CTR/ITR Cams....
