I removed my oil pan today, and the gaskets were all rubber. Then I opened my Felpro oil pan gasket set OS 12705 C-1, and the rail gaskets were cork.

Would all rubber be better? Does anybody know who makes an all rubber set? Should I even worry about it?

RDJ,I wouldn't sweat it,used felpro on my build and have had no problems.I used some permatex goop on the pan side as I figured that would be less straight/flat and maybe more prone to leaking.

Both are available and either will work. I used a skim coat of permatex 2 on my cork gaskets and havent had any trouble been doing that for years.

Biggest trick is to get the pan as flat as possible and don't overtighten the bolts to cut the gasket.
