Any advantage to using nos Pontiac 350 head gaskets.
It appears all normally priced head gasket have 4.2-4.3 openings. I seen some Corteco 20313CS new old stock head gaskets with 3.93 openings. There a couple of different brands available, but it seems there are no catalogs listing the specs. Detroit 20349CS is another.
