What material are the Edelbrock BBC guide plates made from?

These guide plates are constructed from high-grade alloy steel. They are also hardened to 60 Rockwell C, which means they are very durable and resistant to wear.

Why is pushrod support important?

Supporting the pushrod closer to the rocker arm helps to stabilize it. This is important in high-performance engines to prevent deflection, which can lead to inconsistent valve timing and potential damage.

Do these guide plates come with all the necessary hardware?

This part number is for the guide plates only. You will need to ensure you have the correct pushrods and other necessary valve train components for your specific engine build.
