He's got problems!!! a buddys 97Z M6 with cc 305 with ported and milled heads, stock valves, LT's, no tune, LT4 km, 1.5:1 rockers, K-motion 800 springs, k-motion valve locks, k-motion retainers, crane lifters.

Well I will leave it at "Some" peoples straight up is a little different(by a FEW teeth) then mine 
I have seem MANY(over 50) times where the valves are to tight because no one really under stands how to do it.
I would not hold my breath on the not hitting valves on pistons if either of those things have happened Snow Dog
