Used in Ram Air engines.
We carry several different valve sizes for Pontiac engines.
These are common to select Ram Air engines.
Valves are premium one piece forged 21-4N stainless steel which can be used in all high performance applications.
Note- Pontiac engines have many variations of valve head diameters and lengths. It is best to not assume sizes by year or model. Always measure the old valves head diameter and length before ordering.
