What is the main benefit of using adjustable guide plates?

Adjustable guide plates ensure proper alignment of your rocker arms and valve stem tips, especially when using aftermarket cylinder heads or other valve train components. This alignment is crucial for reducing wear and maintaining consistent performance.

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

This specific set is designed for 3/8 inch diameter pushrods and uses 7/16 inch studs. It's important to match these sizes to your existing or planned valve train components.

Are these guide plates compatible with stock Chevrolet Big Block cylinder heads?

These guide plates are primarily designed for aftermarket cylinder heads that feature relocated intake ports to accommodate the splayed valve design. While they may work with some modified stock heads, compatibility is best confirmed with the cylinder head manufacturer.

Product Details

If you're working on a Chevrolet Big Block engine, especially with aftermarket cylinder heads, you know how critical valve train alignment is. These adjustable guide plates from COMP Cams are designed to tackle the unique splayed valve setup found in BBC engines, which can cause rocker arms and valve stem tips to misalign. This misalignment can lead to premature wear and reduced performance.

These guide plates are a two-piece, adjustable design, meaning you can easily set them up to perfectly align your rocker arms and pushrods, even if you've swapped out other valve train components. They're made from precision die-stamped, heat-treated steel with a black oxide coating for durability. They work with all RHS cylinder heads and other aftermarket heads that have relocated intake ports, ensuring a solid foundation for your valve train.

This set is specifically for 3/8" diameter pushrods and uses 7/16" studs. The single fastener design makes them quick to install and adjust, offering a precise way to get your valve train components lined up correctly.
