OP should've stated if this is for a class legal engine.

Sorry I should have mentioned that yes indeed a stock eliminator engine. My current heads have some kinda greyish whiteish looking in there but I can’t determine what it is. It almost looks epoxy like.

You can still fill the heat crossover in Stock Eliminator within the parameters of the rule book.

For sure. I was just agreeing with Mark in that grinding marks wouldn't be a good thing.

Try Mondello Performance or McMaster-Carr industrial supply.

Zinc shrinks .0007 per .100 as it cools. Melts around 785 deg. Shouldn't be a problem.
