64 Exhaust manifold heat riser
Should I remove the shaft and flap in the manifold and plug the holes? Or leave it alone and let it do what it was designed to do?
Engine is fresh 326 stock spec original 2v carb, manifold, heated choke. |

Might as well leave it alone. Won't hurt anything!! Or trade it to someone who wants a working heat riser. Most are froze up and difficult to repair. Just my 2 cents....

If you do keep it make sure you keep it freed up and lubed. In Florida you really don't need it though as it only aids in warm up. You used to be able to buy the correct lube from any GM, AMC, or Mopar dealer. It is not just penetrating oil. It has a solvent and graphite in it. It was called heat valve lube.

'64 Exhaust manifold heat riser
I removed the flap inside the manifold, but left the shaft, counterweight, spring, etc. It looks original from the outside, but I no longer have to worry about it binding, rusting shut, etc. I realize the choke function is compromised, but it has not been a problem for the past 38 years.
