Default Exhaust plug for the intake passage

Is there any kind of material that could be placed in the exhaust passage that crosses over through the intake? That's a big hole going from the exhaust valve chamber to that passage. That would eliminate one source of heat going into the water jacket. Will the plug (penny) do the same thing by stopping the exhaust flow? Thanks, Ed

Two pennys will stop the heat riser through the intake manifold. This will not have any effect on the heat in the water jacket. If you have heating problems you need to look somewhere else.

As stated blocking the passage you described will not help cooling system overheat , I always blocked mine on a dual exhaust set up to change the exhaust notes and eliminate heat to the base of the carburetor,
I decided the best way for me to do this is to use the same year penny as the engine,lol, the new pennies tend to disappear after a while.

do not use the new copper plated zink pennies, use an older copper one in the 60.s

I have always plugged the holes with a plug you get at auto parts stores. They look like mini freeze plugs. 3/4 inch size works good.

I am now running un-plugged and it doesn't sound as nasty, but it sure runs better in the cooler weather. It actually sounds like I installed mufflers on my roadster. It's still loud, just not harsh.

AV8paul,
Just curious do your exhaust/tail pipes have a crossover or do you run straight exhausts on each side?
