If it's a carb 600 rev they should, the SDI's have the injectors in the ports so you may not want to screw with them.....but the only difference that I know of was the reeds, they are offset and angled differently to clear the REV bulkheads. Aside from that, you would obviously have to use your engine plate, but the only thing I'm not sure of is the ignition system, they might have changed up the plug that runs to your MPEM, but if they did, you could probably just either build a little plug adapter, or swap the plugs.
