the problem i had with one of my big blocks(in a 73 camaro) was a small air pocket (in each head i assume) and was always overheating.my cousin worked at at radiator shop and told me he could help out,we pulled the car into his step driveway so the radiator cap was much higher then the engine.then burped the system and refilled it several times till the water just flowed in the radiator and wasn't pushed out anymore.after that no more heating issues

The 65-70 oil pressure cold is not unusual, but if it's staying that high when hot, it sounds like someone put a high volume pump in the engine. This is usually not needed, and the only drawback is that it tends to pump an excessive amount of oil up into the top of the engine where you can then get slightly excessive valve guide oil consumption.

If your water temps are that high than your oil temps are more than likely 20* to 40* higher.
IMO that's to high for oil temps and water temps should be at T-Stat setting or you don't have control of the temps.
