I am planning a 2BBL intake carb swap for a Holley intake and 4BBL carb.
Last time I performed this swap, I used a metal Fel-Pro valley pan gasket, shellacked the gasket surfaces and used RTV on each end.

But, I've been reading and studying some on this topic and now I think maybe there could be other options/better methods.

So, my question is: What do you recommend for a intake gasket for an AMC 360?
