1. Does the 964 3.6L engine require copper base gaskets between the cylinders and case, or does it only use the o-ring?

2. When looking at the 964 pistons, I don't see a good mark to indicate how the piston should be oriented when installed. What should I look for on the piston to determine the proper orientation for the piston when installing.

Thanks,

Brian
