340 with edelbrock heads overheating

George Jets said
Edelbrock 340 aluminum heads are recommended to use their Edelbrock #7326 head gaskets with a compressed thickness of .050 ths.

The Felpro 1008 head gaskets have a compressed thickness of .039 ths.

That is .010 ths difference between the 2 head gasket brands bringing the valve to piston clearance .010 ths closer using the felpro 1008 head gaskets.

That along with a slightly higher lift cam > valves kiss the pistons?

That's just it. They shouldn't. There should be a mile of room. Something's missing somehow. Like the deck clearance of that combo. I'm really curious about that. Although it appears those pistons are the 72/73 style, "WHERE" do they sit at TDC? Without that info, we're all just guessing.
