I recently was told that the cork/rubber mix gaskets are best for aluminum valve covers and OEM oil pans. Any opinions? I thought rubber was best.
Best type of valve cover and oil pan gasket

whatever OEM is, unless your leaking more frequent then expected.
Fel-Pro rubber gaskets have served me 150k+ on the valve covers without a leak, it is thicker and more pliable then OEM for my cars.

FelPro is the one to get.
I have had best success with Fel-Pro, both cork and rubber. I dress them with Permatex Aviation #3. Comes in a small bottle with a brush applicator that makes it a breeze. Dab of FIPG on sharp corners if applicable (like 1/2 moon for cam shaft).

I keep sheets of the cork/rubber stuff in different thicknesses for those items. I cut and punch what I need and use gasket shellac.
The Corvair is tricky because it is a flat pan, so there is always oil over the joint.
Also have the paper and fiber type in different thicknesses.

Felpro for the win
OP wants to know the type, not the brand... Sometimes there are a couple options offered from one manufacturer like cork, (of varying thicknesses), cork/rubber and/or rubber.
Depending of the application, I really like Fel-Pro black cork/rubber gaskets. They're cheap and really seal well- sometimes better than the comparable molded rubber.

That's exactly what I was asking. I see Felpro makes a cork/rubber mix gasket that I thought might be good but have never used. There must be a reason they make them as an option.

I never got much life from cork or blended ATF gaskets. I use OEM unless the specific application has a problem.
