Which way should my Pistons/rod point?

I hope this picture comes out bigger than the last one I uploaded
Actually if you look at the pix in post #16, the reliefs are indeed NOT the same size. Being this piston is numbered 8, the large relief will end up under the intake.....which makes sense. Maybe that is why the pistons were numbered.... to help you sort them properly. My hat is off to Famous Bob for mentioning this.
