I used a cam bearing install tool, measured the cam bearing journals and matched the measurements up to the correct bearing. I installed them with oil hole in the four o'clock position from the top of the engine. I did get the oil pressure and the overheating problems solved. The oil pressure was a mistake on my part and left the oil galley plugs out of the front of the motor behind the cam gear, the overheating was due to a defective clutch fan I now have 50 psi of oil pressure at an idle from a fresh start and warmed up. The engine also does not climb above 180 with out a thermostat installed which it is getting as soon as I get to the store today. I would like to say thank you for all the help, I know I made a stupid mistake one that I can say I will not be making again in the future. And I am still going to build another engine from my old block as soon as I get it back from the machine shop with all the final specs.
