High Oil Pressure

I changed my oil this weekend. I put in 20-50 out of curiosity. i had seen some threads on it and tried it. Took it for a drive and the oil pressure was way up. it normally runs around 50 warmed up and at 2000 rpm. now it is staying at about 70 and pushing 80. assuming the sending unit is right, should i worry about this high of pressure? i assume it is the greater viscosity of the oil.
thanks

I would worry about wearing out your distributor gear (if it's stock) or oil pump.I also read on HESCO's site not too long ago that oil pressure above 60 causes a loss in hp.

i just started to run 15w40 in mine . when it first starts up the pressure is high but when it comes up to temp it runs perfect . i also run lucas in mine . it has higher kms and seems to like this oil .
