Its 30°/32°, I believe it should be fine
My sleeper is too hot and can't understand why

Re: My sleeper is too hot and can't understand why
First, your engine is larger than the engine driven fan can cool. If it was a D engine the fan is probably too small. Add an external oil cooler either in the front of the car behind the front panel or with a powered fan and above the transmission. If it were me I would get rid of the cooler on the engine and put only an external cooler with thermostatic controls. Get a transmission oil cooler for a Chevrolet 350 1996 Impala SS. It cooled these just fine and it used hard piping. If you put it in the front of the car, make a box so air coming into box and going thru fans has to go thru and out the bottom of the cooler. These engines were air and oil cooled. You could also add an additional oil tank to hold cool oil that could be added to the circulating oil to reduce the mass temperature..
Oil pressure is unrelated to the cooling issue. The pressure relief should be opening before 60 psi though. I suspect that someone put a stinger spring in the relief or added a washer or two to make spring stiffer. Check this; Too high of a pressure can damage some bearings.
My 1972 European Super Beetle has a magnesium engine case. It is 1300cc that can be enlarged to 1800 with simply a barrel and piston change. I would eventually like to take it to a real 2.0L.
If you are concerned about A/F ratio put in an O2 sensor in the exhaust. It will tell you if it is running lean at high rpm. The O2 sensor will be handy when you decide to put in fuel injection.
You can use a thinner viscosity oil but make sure it has the zinc additive for the mechanical lifters and cam lobes.
