Okay, so I dont know if many of you know but my 241 heads were swapped out for 806 heads (unfortuanately). I dont know why the owner(s) would do that but w/e. Anyways...im starting to wonder...what if the 806 heads are ported? How could I tell? Anyway besides taking the intake manifold off and looking at the runners? I cant get ahold of one of the previous owners..dont know how.

any help/advice on how to check?
