It may have something to do with your choke or fuel mixture being to rich or lean. I know the fluid heat riser is supposd to take place of the original when installing headers but there may still have to be some carb adjustments needed.

This may be a dumb answer, but did you check to see if the intake is cracked just below the carb? I was trying to find a vacuum leak that was causing rough idle until warm. Turned out the bottom of the intake was cracked and would act as a leak until the manifold was warm enough that the crack closed (my guess). If yours is cracked, you could be letting a small amount of coolant into the intake. Just a thought.

You might want to check and see if your idle fuel cutoff is working properly. Maybe you didn't reconnect it after the manny swap? Will it run off idle? What is the temperature? Like outside? :)
