piston to valve clearance on a b20/vtec with stock pistons
ok i have the 8.8 cr pistons in my b20 now and i want to put in b20z pistons (9.6:1) in my b20 when i do my vtec conversion (prolly with a b16a head) this will put me at 10:1
basically will b20z pistons hit the valves with no advance of timing? ive been looking for answers for days now and i cant find anything for sure..
as far as claying i would but i dont have a head yet or pistons.. i just want to know if phk pistons will work before i order them
and yes i know the best route would be forged pistons but $ is an option here so i want to know if these pistons will work not your opinion on what would be a better setup.

I thought on a Z they would hit. But you could dremel out the valve reliefs a bit and they would work. How much though i'm not sure.

im pretty sure you just need to widen them to fit the larger vtec valves ie there made to accept a smaller non vtec valve
