Which way should my Pistons/rod point?

So far the flat top ones I have seen have equally sized reliefs on both sides. The KB's are all that way as are Speed Pro's....flat tops, that is. The mfr's pix looks that way for this, but may be a stock photo. So, yes, you and TMM are right; a pix from the OP is for sure the best.

You are correct that when there are two valve reliefs, they go to the top of the bore.

Funny how the manufacturer's web site does not post a picture, but other ones show that they are two valve pockets on the top of the piston. But you are correct that those could be a generic stock photo...

Then he needs to make sure that the squirt hole points toward the center of the engine and the anchor slots go to the outside. So you would pin the rod so the squirt hole is on the same side as the valve pockets and the anchor slots go toward the side of the piston without the valve pockets... Then when you install them in the bore, they will point to the center of the engine, or opposite bore...

Always make sure that the anchor slot on the rod and cap mate up on the same side. Not opposite each other, they work together...
