Cometic fiber valve cover gaskets for Buick LC4/LC9/LD5/LK9/LN7 V6 engines use race-inspired materials to exceed OEM sealing performance. Constructed from .094" Kevlar fiber with a fully cured nitrile butadiene rubber binder and a steel torque-limiting frame, they resist over-tightening, high vacuum and blowing out while offering improved durability and fluid resistance for stock or staged engine builds.
