I think you only have to plug the oil pressure sensor hole

or put a 45 or 90

Depending on the style of intake you will have to change the valley cover bolts to a button head.

We always just chop the little stand off where the oil psi sender goes. Then weld it closed. Nothing else needs to be modified. Just make sure you don't switch your vacuum line around. If you need another spot to put your oil psi sending unit, right above the oil filter is where I would go.
