Ford 302 Valve cover gasket

I blew a valve cover gasket yesterday in my Mustang (91), and don’t know whether to go with cork or rubber. The car is a street set up, N/A right now but will be boosted in the near future.

So should I go with cork or rubber, and why?

Thanks in advance.

Rubber…no question. Seal great and are reusable.

i told you rubber you fag

Didn’t your dad always tell you to use rubber?
