I am waiting on some custom gaskets rom Cometic bofore installing the heads. I went with the gpi piston rod combo mainly because you have to pull the motor on these cars to do a cam swap.

I checked a couple of my old rings and found the gap to be right at .012 on all of them. Of course, my block has been very lightly honed - my machinist said he did the lightest possible hone in order to maintain the .005 piston to cylinder clearance recommended by for my Diamond pistons. A .001 bore increase equates to .00314 increase in ring gap, so I was probably around .009 stock.
