What is the purpose of a guide plate?

A guide plate sits between the cylinder head and the rocker arm. Its main job is to keep the pushrod centered and prevent it from wobbling or contacting the pushrod hole in the head, especially under the stress of high-performance camshafts and valve springs.

What size pushrods and rocker studs does this guide plate work with?

This specific guide plate is designed for 5/16" diameter pushrods and 7/16" rocker studs. It's important to match these dimensions to your engine's components for proper fitment and function.

Does this guide plate come with any hardware?

This product is for the guide plate only. Any necessary hardware, such as rocker studs, would need to be purchased separately if not already installed on your engine.
