sbc 350 Head Gasket question
I had my aluminum heads at the shop getting new seals, springs and the valves ground and now need to put it back together. The former gasket had a .038 gasket thinckness. Which gasket would be best for me to use. The engine is a 350 bored .030 with aluminum TFS heads. Deck height says -.001 on the paperwork. I do not see any 4.030 bore gaskets so I am assuming they must use a bigger bore on the gasket than the actual bore of the motor? Is this right and which gasket should I look at getting.
