SBO 350 head gaskets ?
 

Where can I order or find (.020 - .014) or thinner head gaskets for a 1972 small block Oldsmobile 350?

I think Cometic makes them as thin as .030". You could look for someone that has some old NOS gaskets that were .014" thick, www.442.com would be a good start. If it's a Stocker, you can cut the deck under the .002" NHRA spec., creating positive deck clearance (pistons out of the hole), and make up the difference with a thicker than stock head gasket.
