Some of you guys are confused. PUSHROD LENGTH is adjusted to maintain VALVE CLEARANCE "lash" when adjusting valves AND to maintain decent rocker arm geometry. IT HAS NOTHING TO DO with piston to valve clearance. Pushrod lenght is set WITH THE VALVES CLOSED
Piston to valve clearance is determined by cam lift, by valve timing, by the type and height of pistons and deck. Unless I mis--read the type of cam you posted you have very little valve/ piston clearance.
If you need more valve / piston clearance you need to
go to a lower lift cam
go to lower ratio rockers which also lower the lift
Buy different pistons with deeper reliefs
Figure a way to cut deeper reliefs--not a backyard project for the usual shadetree--these must be milled, the pistons re--balanced and quite possibly the engine rebalanced
I'm starting to wonder if this entire question is not mis construed. Maybe you have more piston / valve clearance than you were told?? In any case pushrod length is NOT the answer
another way to change valve to piston clearance is to change the cam timing. moving the ICL around can drastically change V-P clearance.
