So while cleaning up my gross 454, I noticed what appeared to be extra gasket beside the carb thermostat choke. I peeled it back and there’s a hole in the head there which has me puzzled. It’s the factory intake and heads. Did the gasket just cover this up? Any information is greatly appreciated.

Yep i found a pic of the 290 head and the intake manifold gasket last night which showed the odd black hole void to no where. I just was confused when i uncovered it. Its getting new gaskets anyways. Thanks guys!
