that is the same head gasket I use in most of my BB Mopar stroker motor pump gas builds

My old pump gas 517 C.I. Duster motor made 687 HP with a set of Eddy CNC ported RPM heads on Oregon pump swill on a DTS engine dyno in Klamath Falls ,OR at 4300 Ft. above actual sea level, I switch heads to a set of Indy SR Max wedge ports and those heads made 727 HP 2 weeks later with every other part the same including compression ratio, intake and carb, camshaft, lifter and rocker arms
That motor had 10,78 to 1 compression ratio and a Indy400-3 intake with a Holley List 3 9375 1050 CFM Dominator carb, Comp Cams solid roller cam that was 260@.050 with .420 lobe lift on the intake lobes and it had 266@.050 on the exhaust lobes with .409 lobe lift

My message is those are good head gaskets for pump gas street motors with less than 11.0 to 1 compression ratio
