is 20/50 oil really needed on a fresh engine

Having just rebuilt my engine I am concerned with too much oil pressure...good problem to have as apposed to the opposite:-)

Oil pressure is perfect when the engine is at temps. Basically getting close to 2X RPMS (3,000 RPM's = 60 oil pressure).

When the engine is cold I really have to short shift to keep pressure from pegging. As it gets cold outside I see this being a bigger issue.

So my question is, on a fresh engine is thick 20/50 oil really correct? Might a thinner 10/40 or less be more in line with new, tight bearings etc?

Thanks,

Chris
