So about two weeks ago I finished replacing almost everything in the cooling system. Rad, cap, hoses, thermostat, overflow tank....all had little issues that added to the problem but my biggest problem still remains.

Last thing i can think of is a head gasket...havent done a sniff test yet. It just cant be anything else. I'm not getting any other symptoms of a blown head-gasket. Tempted to throw in some leak fluid because i probably just get another motor if its bad. Cheaper/less time than a new gasket, surfacing the head, and adjusting valves. When i rebuild the engine the head had some warping but it will still within tolerances.

 

I think you may have just answered your own question.

Some warping may be indicative of some leaking !

 

after you fill the cooling system, how are you burping the thermostat?

pressure test the cooling system and watch for a pressure drop. if you see a drop in pressure but no visible leak. pull the spark plugs out and inspect for coolant in the cylinders. or start and run the motor with the rad cap off and watch for a stream of bulbs that smell like exhaust. pressure testing the system is the better way to do it
