Default 408 head gasket size and thickness
I have a 408 with 4.030 bore 4 inch stroje 6.125 rod -20 cc pistons and lq4 block 63 cc heads. I had .051 head gasket on it but going to change to .080. How many points is this worth? Looking at these gaskets from spdc SDL408580
Cometic 4.085" Bore .080 Thickness MLS LS1 Head Gasket.. Will they fit and how much will it lower compression Thanks

I would recommend not compromising quench in order to lower compression ratio.
