Chevy Valve Cover Heights
Chevy valve covers come in different heights to accommodate various engine setups and components. The height of the valve covers is an important consideration to ensure proper clearance for high-performance valvetrain components. Here’s a summary of the information gathered from the search results:
– Taller Competition Covers: Chevrolet Performance offers taller competition covers that are designed to easily clear high-performance valvetrain components, minimizing the chance of oil leakage.
– Clearance for Performance Components: Performance valve train components sometimes require taller-than-stock valve covers for clearance.
– Variety of Heights: There are both short and tall valve covers available for Chevy engines, with the tall covers designed to accommodate specific engine setups and components.
In summary, the height of Chevy valve covers varies, and taller covers are specifically designed to provide clearance for high-performance valvetrain components. If you have specific performance components in your engine, it’s important to consider the appropriate valve cover height to ensure proper clearance.

Fancy and expensive valve covers do not increase HP.
