I didn't have to do anything to get the clearance where it should be. I used ARP main studs and they include a sketch to shorten and counterbore the oil tube spacer so it sits on the stud correctly. I did that and the clearance worked out to be 0.270". Moroso recommends 3/16" to 1/2". No oil pressure issues so I guess it is fine.
Ahhh should have thought about that. I am on the stock main hardware still.
