Valve cover gaskets, what kind? Rubber or cork?

[6 Nebraska IDIs]

I've used both, cant find cork anymore, so I was wondering if the rubber is better or not?

I always prefer rubber.No contest.

Rubber is definitely better for most applications.

I use rubber ones and coat them with indian head shellac, tourque twice and so far no problems.

I use Permatex black silicone and thats it....lay a nice bead down. set the valve cover on and press lightly. Wait about 15 - 20 minutes then torque down enough to make the silicone ooze out a little and thats it....done like dinner and no leaks...


OH YA...make sure that the VC and head are both basically hermetically clean prior to laying on the goo!

Rubber and FelPro are my choices.
