How do you know its burning coolant at startup?

it seems to smoke when it warms up. im thinking when the thermostat opens? it has new intake gaskets head gaskets exhaust gaskets and com tower o rings. guess ill take the head off again but i didnt see a crack when i looked the first time i took the heads off. so im gonna pull the drivers side again and look. (the gasket that blew) anyone have a spare head?
Just pull the exhaust off and look up into the exhaust port from there. No need to remove the head. If it stops smoking after warm up it could be residual crap in the Catalytic converter. It's common for them to smoke for several days or weeks after a HG change. If it was actually burning coolant the cloud would get thicker after warmup. Drive it for a few weeks, watch the temp, and see if you are actually losing coolant over time. If you are not losing coolant you probably are still burning junk out of the cat.

At least thats some good news.
COmpression test, then do a coolant system pressure test.

and another question, did you use OEM intake manifold gaskets? IF not, the that COULD be your problem right there.. but a coolant system pressure check would be called for before doing all that work again.

It sounds like there is a good chance that you had no CHANCE to see smoke before the overheat, in which case the answer to my question may make no difference..
I hope nothing awful has gone wrong, but the only way to proceed is patiently and logically. sounds like the next things you need to do are
1. drop exhaust and check for exhaust port crack in the head
2. check cooling system pressure (or maybe just replace the cap.. they are cheap enough.)
3. compression test.
There may be other things worth checking before going so far down the road of "OMG did we blow ANOTHER headgasket," but I just wanted to be clear that I would NOT be umping to that conclusion yet.. BUT there is a minute possibility of it, if the engine overheated.

You say it was definitely leaking coolant into the cylinder; that much was obvious from the smoke. What evidence did you discover that led you to the conclusion that it was leaking into the cylinder?

coolant in the cylinder when i pulled the head off. also the head gasket was wet. intake manifold and IM gasket are both good. so if my head gasket is wet....? also is it possiable if one of the coolant journals is cloged and that rerouted coolant and forced it to the HG?
I think I'm gonna call a spade a spade and agree this was a headgasket issue. If the cracks were in the exhaust then the water would not be in the cylinder. It would be only in the exhaust.
My one question is are you sure that that water didn't just fall down that cylinders intake port when you removed the manifold? If you're sure that's not were the water came from then I think this is a head gasket issue. Did you have your heads surfaced originally? If not I would do them and Definately check them either way with a straigh edge.
