402 big block heads ?

[bo-w]

hollo all , im fairly new here and have to say this place rocks ! great info and some really cool builds.So for my question, iv got a 72 20 custom with a 402 bbc and was wondering weather the stock heads are peanut port or oval or what , I'v done some research and not gotten a clear answer. i suppose i could get a gasket set and pop the valve covers and find the numbers , but figured id ask first. well thanks all for the great forum . oh and can anyone recommend a intake manifold that works well with stock heads ? im looking at doing a carb, intake and possible header upgrade on the old monster.
