You'll need gaskets bigger than 4.030 bore, like 4.060 +
Always run .030 bigger than bore at least

Acturally Pred. A 408 is only a 4.030 bore so a 4.060 gasket will work just fine.
Maybe even look into the GM L92 head gaskets. The bore on the L92 is 4.060 and the gasket works great.
Call one of the local sponsor's.
I perfer SDPC and they can get you a set out right away.
