How do you seal your small block intake?

The little head gasket tabs get neatly trimmed.
the cork gaskets go in the trash
A generous, but not ridiculous bead of silicon takes their place.
The head to intake gaskets get coated with a gasket maker like indian head or permatex. NOT silicon.

That's interesting because I only ever use RTV and NEVER have leaks
IMO that gasket maker stuff makes a much harder mess to clean next time.
