Overheating

[BOOSTnTx]

Every since I blew a head gasket I have been having a overheating problem. I replaced the thermostat and checked that the fan is coming on. Their are no leaks and antifreeze level is full. Also notice that the warmer the temp gets the lower the oil pressure is. I ordered a new radiator just in case the stock one is stopped up. It overheats just at an idle and the temp just keeps climbing. Any help guys?

Lower oil PSI in hot weather is normal. If you have the 87 factory radiator I would change it out as blockage in it I bet is heavy. Good luck!
