after engien gets hot, disconnect fans so they won't run an dput hand in several spots on radiator. if you feel any cold spots then rad is no good. it should be warm/hot all over. other longshot possibilities are head gasket installed wrong or thermostat upside down. but normally the rad is bad also check rad cap pressure it may not be holding what it is supposed to.

I installed the headgasket with the additional whole on top of the oil pressure switch on the block, which is correct right? I hope its the radiator because it's a pain to pull all that out again. Funny thing is that i had done the exact same thing on two exact cars (other than one being a 91) and the reults are with similar issues. oh boy.

Discovered the Top hose hot and lower is cool. Some cracks in the exhaust manifold smoke out and look wet. The fluid just seems to sit still no going in or out in radiator. It takes about 5 min to heat up.

No flow... check thermostat, air in system, and possible blocked radiator.
