___LS vtec __ Will Pr4 pistons hit b16 head valves?
b18a block with pr4 pistons stock rods w/ b16 head.
<FONT SIZE="4">Will the pistons hit the valves or will it be ok? </FONT>
I've been reading yes, then no's. I've asked people and some said yes and some said no...
<U> Will it hit? </U>
Thank you for your time!

just swap em out bro instead of dealing with the problem. you need pistons with bigger valve reliefs.

the problem is money. I already have these parts. If they work I'm happy using them. I'd rather just use what I have.

no they will not hit and if you plan on boosting you do not want to put p30's in b/c you want a lower c/r. i don't know what your plans are with the motor. I have a boosted lsv(b16 head) with pr4 pistons and i have had no problem boosted and long before i boosted it.

it all depends on how much lift the cam you are using has. the only true way to tell if you have enough clearance with any piston/cam combo is to clay the motor.
