930 Piston Pin Offset

I received a 930 engine in pieces ready for re-assembly. The pistons are stock, there are no valve reliefs, and it is apparent to me that the pins are offset. I have not built a Porsche engine before so I want to get it right. Each of the pistons are stamped with a '2', I think indicating the factory sizing.

My question is with respect to installing the pistons on the rods. Since the pins are offset and there are no other marks to indicate which way the offset goes would you be able to tell me how to assemble the pistons on the rods so that the correct offset is accomplished.
