Other than one piece oil pan gaskets, I'm not sure which type gasket you're refering to. I only have the part # for the PermaDryPlus oil pan set:
OS 34509 T Oil Pan Set
GM Prod. V8
...265,283,302,327,350,400 Eng., 1957-74
Gasket Set Includes:
1- 34509 T Oil Pan Gasket
4- 95560 Oil Pan SnapUps
14- 95685 Oil Pan Bolts
14- 95686 Star Washers
4- 95687 Oil Pan Bolts
4- 95688 Start Washers
PermaDryPlus gaskets all come with instructions that say to NOT use any sealant which would ruin the gasket's sealing abilities. (I like that part

)
I'm not sure if Felpro offers just a PermaDryPlus oil pan gasket without bolts at a lower cost.
