I haven't seen a Ross piston for a wedge that will handle .700 without fly cutting pistons...Better off doing it now instead of fixing a dropped/bent valve..

My roller on my old 542 was 274 and 282 and they were fairly even in clearance with the exhaust having more of coarse It is common now but the intake centerine procedure is the same. I degree intake and exhaust often. And we have had brain fart days where we started with the exhaust lifter and we scratching our heads?? then the oh S$$$ we're in the wrong lifter. If your using seat to seat lobe lift .033 is eqaul to .050 at the valve seat so I do
that and .100 before and after Max lift to be sure.
If your shooting for 106 ATDC intake the exhaust lobe max lift will be at 114 ABDC

Sounds like we are all pretty sure fly cutting is the answer. now how much can safely be cut or how much is a minimum thickness left after cutting? has anyone cut with shortblock assembled? i know isky and others make a tool for this but is it safe and accurate? what about the balancing? thanks again for the replies
