That is normal. Once the oil is warmed up the oil pressure should drop some at idle. As long as the pressure builds along with the RPMs you are fine. One of the local engine builders told me many years ago that as long as you have about 10 psi per 1000 RPM all is good. This is coming from a Ford guy that mainly builds race engines.
