heads don't matter, it's the block. like stated above, a 2004 block should be the 2 sizes. With that said, I have heard of some very early 2004 blocks still being a 3 bolt version. Easy way to check is just get a screw driver and stick it down the bolt holes and see if it goes in the same depth in all of them. Very easy to check.
