IMHO,

You aren't losing 35-40 psi at the lifters. It might be costing you 6-8. I'm not suggesting you shouldn't do it, it just might not be all that you hope it is. You may have a standard oil pump installed instead of a HV pump.

I had a similar problem on a fresh 428. My oil pressure was 45-50 cold, 25-35 hot. I pulled the pan and the shop had indeed installed a standard oil pump. My oil pressure went to 70-75 cold to 45-55 hot.

Good Luck
