question about heads...

I been looking for some little things to help my poor 2.3 lima out power wise. Im lookin at skipping the bolt ons and move right to the head problems, considering they flow like crap, and i got to reading around and read that all 2.3 and 2.5 heads will bolt right on to each other...anyone ever heard of this or anyone ever seen it done...what kinda flow would that produce?

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.
