That is a PIA. The fun part with both of those was that the pistons were NOT destroked, so after decking the blocks they kinda stuck out a tad too much. Putting the head on with it that way would be embarrassing and get me phone calls. So I simply milled off some of the outer raised circle on the piston head, effectively raising the compression ratio by about .5 to one plus the gain from the overbore, those both came out to a shade over 10.1:1 which made me nervous.
um HELLO removing material from the PISTON does NOT raise compression it LOWERS it
