I always thought cork sucked. I didn't know anybody preferred it.

Cork is 1800’s technology, it works fine but there is better options nowadays.

Like said of everyone above the cork IS NOT preferred by anyone - cork will degrade and allow oil to permeate through.
Good gaskets are worth it - don’t bargain shop in this area.
