100+ psi oil pressure

Fired up my newly rebuilt 360 and have 100+ psi oil pressure at idle. It appears this problem has happened with other AMC motors, but would like some help determining the cause. Timing cover, pump housing and pump kit new. I am going to see if plunger is sticking this weekend. Some say to take out plunger and spring and momentarily fire up motor to see if oil pressure says at high level. Any thoughts? Thanks for any help.
