I just bought a used Performer intake for my Olds from Tom at JBP.
I also have a new set of Felpro gaskets like this:

Notice there are no holes for the exhaust crossovers. I was going to buy the plugs to block the crossover in the intake but was wondering if this kind of gasket alone would be sufficient to block the crossover, or would it burn through?
