Mastodon Chevy Big Block Steel Core, Rubber Valve Cover Gaskets

Reusable Big Block Chevy valve cover gaskets in steel-core rubber. Built to handle the heat and oil pressure of the BBC and the wider cover footprint, with a steel core for shape retention and a moulded rubber sealing surface that returns to its proper position after every removal.

Sold as a pair (driver + passenger). The right gasket when you've got an active engine — distributor swaps, valve adjustments, or BBC valve covers that need to come off more than once.
