Default Which head gasket needed???

Im assembling a 6L iron block which was bored to .030, what size (bore) of head gasket should I use? It wont be a turbo or NOS car; just a Z06 cam/243's heads car for daily driving and occasional strip days.

Before ordering, make sure you measure the combustion chamber as well. Sometimes this will dictate the gasket bore size rather than the cylinder itself.

He means the outer diameter of the chamber.
