Default Low oil pressure

Hoping some flathead gurus can offer some tips for a novice. My '41 engine doesn't Carry good oil pressure, maybe 25psi cold. I bought the engine used, brought it home, and built a cradle for it and a radiator. First thing I did was drop the pan and clean out 1/4" of gray peanut butter out of the pan, pickup, and pump. I put fresh 10-30 in it and to my surprise got it fired up and idling well. The low pressure concerned me since my 8ba runs 60psi cold. So I installed a new style Melling pump and F-1 style pickup tube in the pan. Same result. Am I missing something?
