I like the 12.5 wiseco the pockets are good enough to run any big cam

how big do they need to be to run those cams

 

[k20coupe]

Im sure it be able to take it
From what I understand the malhe will last longer for the tighter clearance and will be a better dd piston

the amount intake relief really depends on how much VTC you wanna run and of course the lift of that cam. .235 is only enough to run k2s while running 50 degrees of cam angle. With K10s you probably don't wanna run no more than 35 degrees

so how much relief do u need to run the extra 25 degrees?
