yes it would net you a couple of extra hp/tq but since you have the si parts why not just drop the si motor in make more hp and tq that way. and if you have the si tranny laying around you will have better gear ratios. and the only way to drop in the si head on a dx in to convert it mpfi you will also need the computer. if your going to do that might as well do a motor swap.
