head gasket?

[rustyruststang5]

looking to put about 10 lb of boost through my 306. what is a good head gasket to use? does it matter if my block is bored 10 over when picking a gasket?

Unless your block has a nice smooth mirror finish on it along with the heads I'd go to a Fel-Pro 1011-1 gasket and head studs.

The MLS gasket needs a perfectly smooth finish to properly seal, I prefer the Fel-Pro gaskets as I have had Cometics leak between the layers.
