Strange??????????? I just took the SS for a short ride with the new heads on. About 2 miles from my house the temp shot right up to the red area. I pulled right over to the side of the road and shut the car down and opened the hood to cool it off.
Turned the key to the on position (did not start the car) and the temp gague read 210 ish? I let the car sit for 10 min or so and started it up. The temp was back in the 210 range. I drove home and the temp stayed in the normal area the whole time? I did put a new Hypertec 160 t-stat in, but the car is not tunned for it, so I did not expect the temp to be low. Just wanted to state there is a new t-stat in the car.
there is still some smoke comming from the driver side of the car. Sitting in the driveway right now. No drips comming from the car. Oil level looks good.
Could this just have been an air ppocket working it's way out. I did turn on the heat for the ride.

sounds like the new t-stat stuck a bit, or the air pocker needed a little burp. check your coolant leavle andsee how she looks once it cools a little

From what I understand LS1's dont have a bleeder like LT1 cars so getting air out is a bit trickier, I would definitly do my best to re-bleed, this is the sort of things that can ruin a motor. Has there been any previous history of the coolant temps doing this, or was it just after the swap.

I had the same problem, it was air in the system somewhere. Let it cool off, then crack the crossover tube a little loose and start the car, that will give the air an easy escape route... worked for me. Probably have to let the car sit and idle for a little while to get it to work, at least I did.
check to see where the smoke is coming from before it cools off.. could be something as simple as a loose coolant plug or line or something.

sounds like the awsome ls1 airpocket dave.
did you drill the bleeder in the tstat? if not its even harder to get all the air out. idk if you remeber how much of a bitch mine was to bleed before i got the elec water pump. some are a PIA!!!!!!!!!. check your level and should be ok as it was ok on the ride home.
just dont make any long trips till a few short ones are 100%

I figured you probably have typical coolant everywhere... that's normal.
It's an airpocket probably..... the T stat will go nuts for a while until it's out. Start the car and let it idle for a while with that crossover loose, and when it stops steaming from there and it's just coolant it should be good to go.

Thanks Keith. 
I did not drill anything on the T-stat. I thought it was an air pocket, but scarry still the same.
Injectors will be here tomorrow.

Congrats on getting the heads on. When I fill mine I leave the front crossover hose undone until coolant comes out, then I plug the hose back in, then start it and top it off. Like everyone else mentioned, your's was prolly just low on coolant.
BTW, what kind of injectors are you getting? And how's that install going to work? Will you install them at the shop, then tune? My understanding is that the car will run like **** with different injectors if not accompanied by tuning/calibration.
BTW, by the title of this thread I thought you got a rear end lol.

You really don't need a bleeder valve,you just need patience. Start and let the car run while adding coolant as needed.Turn on the heat and let the car run till the lower hose gets hot.All this time you check the temp gauge or you can hear the fans go on high.When the lower radiator hose is hot the system should be all set.Most people only let the gauge get up to temp and think it's all set,ussually the t-stat isn't open yet.So when you drive down the street the t-stat opens and the coolant is too low causing the temp gauge to raise fast.This can also blow a head gasket if not caught in time.
And you do not have to drill a bleeder hole in the stock style t-stat,that is only for Messiere pumps.

you've got to let the car get warmer and when you think it's too hot the t-stat will open and guzzle coolant. 
also good info

OK,
I took the radiator cap off & let the car idel for 30 min with the heat on. The hose from the t-stat to the radiator never got hot. The temp stayed @ 210 the whole time. Coolant level stayed full.
