Correct Oil Filter for SB

This is great. I’m having the same low oil pressure problem with my 318. I had lifter noise on the right bank and presumed it was caused by low psi. I installed a HV pump, but that made no difference. I’ve pulled my motor out and found that the caps in the front lifter gallies are missing. Has any one ever had a problem with a remote oil filter system causing low psi? Because of the headers I couldn’t use a 90 deg. I’ll check all the other things out too and hope to get better psi.
