Edelbrock 4491 - Edelbrock Signature Valve Covers

Engineered for Serviceability,
Styled for Excitement

OE-style breather baffles prevent excessive oil usage through the PCV valve, and rubber grommets for the breather hole are included. Valve covers accept all emissions equipment. When applicable, low profile covers are stock height, and tall are about 1-1/2" taller than stock. Tall valve covers clear most aluminum rocker arms with moderate lift cams but not stud girdles.
