I'm curious your thoughts on the OP's proposed combo. Any concern about the 8.23:1 dynamic compression ratio with iron heads and a pretty wide quench distance (0.051") on pump gas?

I’m with Tim. Better to run a typical .038 head gasket for the quench then tune it up. Carb and distributor. Run the 91/93 octane and be good with it. It’s a good combo. Stab it with the cam for the rpm range you want to be in and let it rip. It’ll be just absolutely fine.
