the heads between them are virtually identical and still flow very poorly. The best thing to do is to actually have a head ported out and matched to the intake and exhast and have the intake manifold al ported out and cleaned up.
The only differences between heads is the intake manifold pattern is different on different versions of the head, but if you get the intake manifold to match it then it is no problem. I would suggest getting a head and intake manifold from a junkyard and haveing it all ported and cleaned up then bolting it on when its all ready with new gaskets all around. If you do it make sure they port match the manifold to the head and also the upper manifold to the lower manifold and the TB to the upper manifold.
