Change Your Geometry with COMP Cams 2-Piece Adjustable Guide Plates

Modifying cylinder heads can result in a lot more horsepower, though sometimes you have to cut or pry the valve guide plates to correct your valvetrain angles. To remedy this problem, COMP Cams has developed a 2-piece valve guide plate that is made from die-stamped and heat-treated steel. The interlocking design ensures a straight and true valve alignment, eliminating the need to pry, bend, or cut valve guides. They are also adjustable inward or outward, and they can even be welded should the need arise.

Official Press Release

Cylinder head modification can net some serious performance gains. However, once the valve centerlines have been moved, you sometimes have to bend or cut stock guide plates in order to compensate. To solve this common dilemma with aftermarket heads, COMP Cams® recently developed an all-new line of Two-Piece Adjustable Guide Plates for high performance Small Block Chevy V8 and 90° V6, along with Small Block Ford V8, engine applications.

Created from precision die-stamped and heat-treated steel material for a closer setting and improved durability, these fully adjustable guide plates feature an interlocking design that enables a reliable and true adjustment in the one axis needed for most valves. This prevents issues associated with prying or cutting the guide plate, which often make it difficult to line up prior to welding.

In addition, these guide plates can easily be adjusted inward or outward for maximum convenience. And for more stability, they can be finish-welded once the final adjustments are made. These performance guide plates work with all RHS® cylinder heads, as well as other popular cylinder head brands in the performance aftermarket, both stock and those that feature relocated intake ports.

For the serious racer or high performance engine builder with aftermarket Small Block Chevy or Small Block Ford cylinder heads, these new guide plates are a “must have” item. Designed for use with studs that have 7/16″ base threads, they are available in sets of eight for 5/16″ diameter pushrods.
