those are the lim gaskets, but dont order from zzp. you can find them for 5 bucks less at rockauto. or advance auto.

you also need a upper plenum gasket, aka sc gasket, its 11 bucks at a local parts store.

and pick up 3 or 4 feet of vac line and 2 new vac T's cause they always break on you when doing a lim job.
