DODGE 5.9L/360 MOPAR SMALL BLOCK LA Cometic Head Gaskets - 22.038cc Compressed Volume (cc)
You already don't have quench with the J head/flat top piston combo, so order up a set of these and do a weekend swap. It will be the equivalent compression wise of the 20cc dished piston that comes in the scat kits. You will need to get thicker intake gaskets, or double the thinner ones.
