try taking the tstat out and I would think this would be it but maybe got air in the coolent. And if you just had it rebuilt an it wasnt doing this before maybe some how your block got junk in it during the rebuild an its plugged up now.

Just curious did you have the heads and block magnafluxed?

make sure you have proper oil pressure. insufficient lubrication can cause it to heat faster than the cooling system can over come. is you radiator hooked up properly. do you have proper flow when the thermostat opens. have you used any sort of leak seal as the can build up and clog up the radiator

Was your block and heads planed? If they arent flat it will continue to blow head gaskets.
