Changed the oil and filter. New oil is 5w-30, 10w-40 before. Slight reduction in startup pressure (65 vs. 68psi) with a mechanical gauge. So, it's not a restriction in the filter.
The long block has about 5000 miles on it and the top end is new. The pump is Melling. The cam is a Lunati retro-roller and I followed those instructions on start-up.
