i don't think it's just as straight forward as bolting on the different heads.. the 4v heads use a different intake manifold (you'll probably need a different throttle body with the intake too), and i think you may even need a different wiring harness and front engine cover. i know i read up on this a while back and decided against it because of all the components i'd have to piece together to make it work. it can be done though, just depends on how much time and money you want to put into it.

You can...but its not suggested because you wouldnt get really any gain out of it because of the lowered compression. If you had an NPI engine then it would but you are going from a 9.6:1 compression to a lower 8:1 compression ratio due to the size of the combustion chamber and the fact that our pistons are dished. But you have to change a lot of crap to make it work.

what about the fact the heads flow a ****load more air then a 2v head
