The Fel‑Pro solid metal‑core intake gasket is designed for high‑vacuum and demanding applications where gasket movement into the intake port must be prevented. Recommended for circle track and drag cars with restrictor plates or throttle stops, and for long‑service engines, it’s tested with numerous aftermarket head and intake combinations. Not intended for emission‑controlled vehicles, it supports cast iron and aluminum heads.
