i dont have time to search, i just ned an answer. i just got wiseco pistons for my ecotec build, 10:1 compression. Are the pistons supposed to have valve releifs or no, because they dont. any help would be great, thanks guys.


horsepower is the force that determines at what speed you hit the wall, torque is the force that determines how far you take the wall with you after you hit it.

im pretty sure stock doesnt have valve reliefs so yes i believe it to be fine.

usually wiseco doesnt put valve reliefs in our stuff unless you specifically ask for them.



I'm tired of wasting my time... now I'm breakin' free.

No the 10:1 Ecotec pistons do not need valve reliefs.
