I had to cut a lot off of the aluminum bracket(A/C mount) to clear water neck. A/C compressor will have to be cut or ground a lot as well. I have a Professional Products Crosswind intake (Airgap clone). Ditto on what Dakota Dan said, you will need the correct timing cover. I have magnum heads so I didn't have any issues there. Motor is still on the stand so I can't tell you how well it does/doesn't work in reality. Mines headed for a truck so I'm not too worried about clearance issues with P/S pump.
