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
Harland sharp 1.65 ratio roller rockers
My message is those are good head gaskets for pump gas street motors with less than 11.0 to 1 compression ratio
