Have a sbc blueprint block that I'm getting ready to drop in a car. When I prelubed on engine stand the #1 exhaust rocker is flooded with oil flow. Most others aren't getting much. Rotating crank doesn't change #1 but may help slightly on others. I had 65lbs oil pressure and would think flow would be equal front to rear, side to side. Is there galley plugs that could be missing or incorrectly installed that could cause this? No way I'm going any farther without figuring this out. Probably be pulling the intake to see what it looks like when I'm priming around lifters. Any ideas welcome.
