Would you slot a SCJ intake to make it work?

I have a 3 barrell 950 vac which has 50 CC pump. It hits the intake so I need a small spacer. Since it going on a shaker Torino Cobra I can't lift it much. Do you think I would ruin a good intake if I slotted it so the secondary butterfly won't hit? It's the SCJ style intake but it came from a boat. Only difference I can see in them is the nipple that goes to the waterpump is threaded.
