I can't find instructions regarding the correct orientation of Wiseso Pistons in the block. Nothing in the Wiseco box or on their website. Before the bottom end is all sealed up I want to double check and make sure I guessed right. On the dome of the low comp 84mm pistons the valve cuts are larger on one side than the other. I guessed the larger ones are for the larger intake valves. This is in a 94 1.8L motor.

Did I guess right or is I stoopid?

I thought Wisecos had a little dot or dimple.

Doesn't Sav run these? He's online right now...

No dot or dimple on these. They are a couple years old and look different than what is currently being made. There is a number on the face. Seems really odd there are no instructions on their website about orientation or in the box.

Larger VRs = intake side.
