I know it is a good idea in big block chevy's, high pressure...no, high volume...yes.

I increased the flow of oil to the heads to better lube the roller rockers and valves/retainers/ and so I only run about 50 psi, but you can be sure oil is flowing like crazy to all the other parts.

But with .0015-.002 clearances on the small blocks I have built I have never had a problem with the standard pumps. They run 60-70 psi all day long, I usually eliminate the casting flash in the oil galleries and return valleys so that the oil returns to the pan faster though.
