What material are these guide plates made from?

These guide plates are constructed from high-grade alloy steel. They are then hardened to 60 Rockwell "C" to ensure they can withstand the rigors of engine operation.

How many guide plates are included in this kit?

This kit comes with 8 guide plates. This is the standard amount needed to equip a complete V8 engine.

What is the benefit of supporting the pushrod closer to the rocker arm?

Supporting the pushrod closer to the rocker arm helps to stabilize it. This can lead to more consistent valve operation and reduced wear on valve train components, especially in performance applications.

About this part

Product Details

Hardened to 60 Rockwell "C" from high-grade alloy steel, these Edelbrock guide plates are built to last. They're designed to support your pushrods closer to the rocker arms, which helps stabilize them. This is especially important for performance builds where valve train stability can make a big difference in how smoothly your engine runs and how long it lasts.

This kit includes 8 guide plates, enough for a full set of cylinders. They're a solid choice for AMC engines from 1966 through 1991, covering displacements from 290 cubic inches up to 401 cubic inches. If you're rebuilding the top end of your AMC V8, these hardened guide plates are a smart addition to ensure your valve train stays properly aligned under load.
