Granatelli 640371 Features:

The Granatelli LS Series valve cover gasket set and seal kit replaces your old, worn, heat beaten, gaskets and seals that promise to leak the first time you remove them. Simply put, predicated on the LS cylinder head design, once they are oil soaked and heat cycled, they stretch and will not go back in. The Granatelli gasket and seal kit are a direct remove and replace installation.

Granatelli 640371 are the gaskets and grommets supplied with all Granatelli tall LS valve cover kits. The grommets will work with tall or OEM stock height valve covers.
