Some people like the Felpro. When I first put the tube headers on years ago I tried the Felpro with blue stripe and at that time cost me $32 for the set. They lasted about 2 weeks.
The #1448 exhaust mentioned above is now about $30 and the intake
http://store.summitracing.com/partdetail.asp?part=FPP%2D1257&autoview=sku is another $16. I can't say for certain that those are the same part numbers I had used, but they were Felpro Blue-Stripe and special order by a flaps.
I got a one-piece, cheap ( $6), paper gasket (looks like asbestos) from PAW (
http://www.pawinc.com/ ) and it lasted about 12 years. I rebuilt the 292, added the alum manifold and 4 years later, it's still good. I looked, but don't see it on their web site. The part number I have is TDP-4268, but the catalog is 4 years old.
Do replace the end pins with threaded studs as LGriffin mentioned. I replaced all of the bolts with threaded studs I scrounged from other heads. It makes it a lot easier to put everything on.
