I need some help with an old Dodge truck.

Take a look at the 4 bolts that insert on the bottom of the exhaust and go into the intake manifold. They are extremely prone to snapping. Also, the areas where they screw into the intake manifold is prone to cracking.

The heat riser in my replacement exhaust manifold was gone. This caused too much heat transferring to the area of the intake below the carb. Once the engine was warm, if you shut it down, all of the gas would “boil” out of the carb, making the truck hard to restart. Gasohol made starting even worse.

I finally put a piece of thin, flat steel (about as thick as a license plate) between the two manifolds. It was a big help.

Granted, I live in South Central Texas, so a hot manifold set on a hot day is more of a problem for me than the possibility of a hot manifold set on a cold day.
