I'm putting an Evo 8 head on a 9 block. I know the balance shafts for evo 8 have a different part number than 9's for MIVEC reasons. My question is, can I use my 8's balance shafts in the 9 block? I've looked up every thread on the 8 head/9 block and all I've found was the difference in oil pressure sensors. I just want to make sure before I get too far in. I'm also not interested in just deleting them either.
