High Oil Pressure >.<

I would check the gauge, IMO gauges unless they are liquid filled are not very reliable, and if you really are getting 100 psi yes that i do beleve is waay to high, I have a 360 stroked brand new, like 30 miles on it with a melling HV pump and it runs 60psi cold, with Shell 15w-40 Rotella, what make is your gauge?? Auto Meter, etc??
