      ok,this is direct from my builder ,who knows his stuff .NHRA min. head cc's is 167.7. Normal volume on a mopar replacement head is 170.0. The orginial head gasket is .020 thick, it volume is 2.4 ccs. the volume of these indy heads 165.5 cc's. By using a .040 head gasket instead of the .020 gasket the head volume becomes about 167.8 or about the same as the NHRA minimum. the compression ratio of a 4.25x 3.75 with the indy head and a .040 gasket with an 88 cc dome is 11.0:1. Most street hemi aftermarket pistons dont have this much volume as the valve reliefs are cut deeper or large lift cams. I hope this info is helpful .
