The Edelbrock #4485 Signature Series Valve Covers are designed for Oldsmobile 350-455 V8 (fits 5- and 10-hole heads) applications. Engineered for function and styled for great looks, Signature Series valve covers have stock-style breather baffles that prevent oil passage to the PCV valve. These quality valve covers accept all emissions equipment, including PCV valve holes. Rubber grommets for the breather and PCV valve holes are included. Matching breathers sold separately.
