What is the purpose of guide plates in an engine?

Guide plates are used in performance engines to keep the pushrods centered on the rocker arm stud. This ensures proper alignment, especially with higher lift camshafts and stiffer valve springs, preventing premature wear on the pushrods and rocker arms.

What size pushrods and rocker arm studs do these guide plates work with?

These COMP Cams guide plates are specifically designed for 5/16" diameter pushrods and 7/16" rocker arm studs. It's important to match these dimensions to your engine's components for proper function.

Are these guide plates suitable for stock engines?

While these guide plates are built for performance applications with higher spring pressures, they can also be used in stock engines if you are upgrading to a more aggressive camshaft or need to replace worn components. Their hardened construction offers improved durability.

Product Details

If you're building a performance Ford small block, especially one that's going to see higher spring pressures or more aggressive camshafts, you'll want to make sure your pushrods are staying perfectly aligned. That's where these flat, one-piece guide plates from COMP Cams come in. They're designed to keep your 5/16" diameter pushrods centered on the rocker arm stud, preventing them from wobbling or wearing out prematurely.

These guide plates are made from hardened steel and finished with a black oxide coating, which helps them stand up to the demands of a performance engine. COMP Cams used stereo lithography techniques to ensure an accurate fit, meaning they'll sit right on your 7/16" rocker arm studs. The rounded contact points are also a nice touch, reducing friction and wear on your pushrods.

This set includes eight guide plates, enough for a full V8 engine. They're a necessary component for any high-lift or high-spring pressure application, helping to ensure consistent valve train geometry and reliable performance for a wide range of Ford vehicles.
