After I replaced my head gaskets and the intake gaskets, I still can smell antifreeze burning and have smoke coming out of the exhaust, is that normal til all the excess fluid runs out? If so how long does it take until everything is back to normal?

It is normal, yes. The time it takes for the smoke to clear out should be until the engine is warmed up. Beyond that, there might be something else going on. Anti-freeze can take awhile for the burnt aroma to go completely away.

What else could the problem be? I had the heads checked by a machinist and there good, and I followed the torque sequence to a T. I could be overly paranoid.

That could be, but lets see what happens here first. The gasket set was the correct set, you matched them up to the old gaskets, yes? You followed a repair manual, yes? How long have you let the motor run after the repairs?

Not long 5-10 minutes, I finished putting it all back together right before the title game earlier, so I called it a day to watch it. The gaskets matched up, I followed the torque sequence from my Haynes repair manual. I also went ahead and replaced the water pump and thermostat. Ill run it in the morning and see what happens and get back to you. Thanks

Alright I ran it for about 45 minutes and it looks like the gasket repair was successful. I think it took abnormally long to push everything out bc the leak was so bad and water built up in the muffler. I checked my dip stick and oil still looks good. Radiator and relief tank havent lost any liquid so I'm gonna cross my fingers and assume its good to go. However I have a new problem, I havent taken it out on the road yet but when I ran it in idle it choked every now and then, and when I backed it out of the drive way it choked real bad and I'm suprised it didnt stall out. Im pretty sure the throttle bodys in right, and I dont have a gas leak. What might the problem be?

I would recheck the basic stuff, timing, possible vacuum leaks, any vacuum lines.
