Anyway to tell if headgasket is in backwards? Anyway to tell if the head gasket is on backwards? I might have put one on backwards but im not going to tear it down for nothing and the ect sensor is going crazy so i dont want to find out by just letting it run and see if it overheats....Any clues to tell me which is the top while the head is bolted down??

If it's an MLS gasket, the easiest way to tell is the metal tab that sticks out on the front part of the gasket. I grabbed a pic for you and circled what I'm talking about. You'll also notice the "front" I circled. Those two tabs needs to be towards the front of the motor, not on the back. You can see them standing over the engine.
Good luck.
Good luck.

When I had the motor out and the other gasket out I couldnt notice any tab or something to identify what I needed. Was hoping there was some secret tip that could tell me, the gaskets I used were the ones I got from advance in their computer made by Felpro....Not a crazy build and wasnt my car so thats what I used...
Only reason I'm asking is the motor I just built is overheating and wanted to know for sure its the hg and not because I didnt burp the system enough or something....
Is there any special way to fill these things with coolant? any bleeder screws?
Could I diagnose my problem with a laser heat gun? compare the front and rear temps of the head to the other or something?? I really dont want waste the money on new gaskets and head bolts

To burp the cooling system, get the front of the engine higher than the rear (lift front of car), and undo the the hose from the crossover steam tube (in front of the intake manifold) and let coolant/air bleed out...
if you attach a clear hose to the crossover (and direct the other end into a water/beer bottle, container, or something to collect coolant) and you will see air bubbles in the coolant as it passes thru the clear tube... when you see only coolant and no air in the clear tube then all the air has been burped out, put the hose back on, and top up the radiator and overflow container.

Coolant may dribble out, just place a rag under it.

Im also going to check the temp of the lower rad hose, if it doesnt get hot with the engine temp I know the thermostats stuck closed.
Tonight I'm going to put the front end on wheel ramps, disconnect the steam tube line at the radiator and see what comes out while its running out, hopefully a mess of air comes out and it stops overheatingggg
