(wanted) Edelbrock 60177 or nicely worked RHS heads

You asked about this before and you're getting the same answer.

Run a thicker head gasket to get your quench distance. Run a .055-.060 head gasket and be done with it. No reason to run the open chamber head even with the piston sticking out .015.

The RHS or closed chamber Ede would work fine with a thicker gasket.
