Heat crossover ????
So I had several steel shim gaskets here. Out of the 5 (don’t know why it’s an odd number) one had a 3/32 hole in it, and the others had the crossover hole the same size as the heads.
I stuffed the crossover full of aluminum foil and used the one gasket with the little hole in on one side and a big hole on the other side.
It is what is is, but I didn’t want to machine the intake for a thicker gasket.
We will see how long that lasts.
