Big Block heart attack

oh isnt a 383 a hemi, new to US muscle cars as I am from australia and have our own holden V8 and chevs the chyslers/mopar cars were not so popular.

BTW got the gasket out and its got 2 gaskets in there.....is this normal practice? its got the hooker fender hedders. I think its a sign someone had issues getting one to seal.
