Prefered VC Gasket

Which gasket do most people prefer? The felpro cork or the rubber? This will be for an iron head with a set of Blue Thunder cast aluminum valve covers.

Are the valve cover rails on the heads machined flat or are they as cast ?

Dove heads. I haven't machined the VC rails

I have had better results with the cork

I prefer the cork

As long as they are installed dry and the gaskets are glued to the covers it will make no difference in your application.

I ended up doing this with the rubber ones.

If they seal the same I might try the cork ones next time. Had to strech the rubber gaskets to line up right which was a pain

Pay a bit more $$ for the ever reusable ones from 'Earls' products.
They are a rubber coated steel frame that will never crush or leak, and you'll never have to buy VC gaskets ever again!!

I have the Cometics on mine and seem to work well after a few heat cycles and cover removals.
