What is the purpose of a pushrod guide plate?

A pushrod guide plate sits between the cylinder head and the rocker arm. Its main job is to keep the pushrods properly aligned, especially when using adjustable rocker arms on modified engines.

What modifications are needed for a 351C engine?

For 351 Cleveland engines, you'll need to machine the old rocker stanchions down to a height of .550 inches and drill and tap the screw hole to accept a specific stud. Refer to the manufacturer's instructions for precise details.

What material are these guide plates made from?

These guide plates are made from steel and have been heat treated for added durability. They also feature a black oxide finish for corrosion resistance.

About this part

Product Details

If you're modifying a Ford 302 Boss or 351 Cleveland engine to use adjustable rocker arms, you'll need a set of pushrod guide plates. These plates sit between the cylinder head and the rocker arm, ensuring your pushrods stay properly aligned. This set from Manley Performance is specifically made for modified 351C engines and Boss 302 applications, designed to work with 3/8 inch pushrods.

Manley meticulously crafts these guide plates from steel, then heat treats them for added durability. The black oxide finish helps protect against corrosion. To install these on a 351C, you'll need to machine the existing rocker stanchions down to a specific height and modify the screw hole to accept a new stud, as detailed in the manufacturer's instructions. This ensures a solid foundation for your adjustable valvetrain setup.
