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.

Yes your right to assume that the double gaskets mean they had a problem with header leaks. Since FW headers are easy to remove, you may want to have the flange suface trued to avoid leaks in the future. Alsp MLS type header gaskets like Percy's and other do a better job of sealing.
