The pennies in the manifold reminded me of to two dimes under the bridge of my dad's fiddle. When asked why they were there, he would reply, "So I can say I'll never be broke."

I don't see why this is necessary except for an all-out race engine. The proper manifolds for those don't have a provision for manifold heat anyway, so why bother?

Blocking the heat riser holes with pennies so far as I know never had anything to do with improving or modifying engine performance.
It was a fad that intended to change the
exhaust sound that some thought was "cool"
