A 351C intake gasket should have an opening in it to support the crossover 
port, right?   I would therefore assume that your heads and gasket will have 
holes, but your intake does not?   Yes, I suppose it's possible that exhaust 
gases could eat up the gasket and cause leaks there.   If it's a concern, then 
perhaps I'd trim a thin sheet of aluminum or steel (slightly thinner than your 
intake gasket) to the size of the gasket opening and secure it to the surface of 
the head with RTV.   That way, exhaust gases run into the patch you've made 
instead of the underside of the intake.

Just a guess though....
