Heat riser or not?

I know there are varying opinions on this.

Should I run a heat riser or not on my 396 bb?

Getting ready to do the exhaust system.

I live in upstate NY but will not be driving in weather less that 45 degrees very often if at all.

Opinions??

I took mine out and did not notice any ill effects. Mostly, after the car sat for a long time, the heat riser would stick shut and if you don't notice, you stand to burn all the paint off your intake passages.

If you're not into shows with judging correctness, etc.... take it off, but don't throw it out.

Re: Heat riser or not?

Intake manifold heat is good for street-driven engines. It improves low-speed drivability, fuel economy, and reduces engine wear. Any carburetor tuning book recommends that it should remain functional.
