Re: Header gasket?
buy both and then return the ones you don't need.

Re: Header gasket?
unless someone sneaked something by me (entirely possible, but in this case highly unlikely) all pre-vortec SBC exhaust ports were the same. You're maybe thinking big blocks...?
Anyway, have had good luck with the standard foil backed paper gaskets (stock type). The trick I have used forever is to soak the gaskets, preferably overnight, in water. Once you run it for a bit of course the water turns to steam and how ever it does it, never had a leak unless the header bolts backed off (this was before man discovered Locktite  ).
