Description
Precision Guide Plates. The Comp Cams GM LS Cathedral Port Head Guide Plates for 5/16-inch pushrods are engineered to ensure proper pushrod alignment in high-performance LS engines.

Construction and Appearance. Manufactured using stereo lithography techniques for exceptional accuracy, the plates are flat, one-piece components with a hardened black oxide finish to resist wear and corrosion. Their precise stud placement and rounded contact surfaces provide optimal contact and longevity in demanding environments.
Installation. Installation is straightforward and requires no drilling. The plates fit securely over standard 8mm rocker studs to accurately guide 5/16-inch pushrods.
Warranty. This product is backed by a 12-month warranty for quality assurance and durability.
Application. Designed specifically to fit 1999-2013 V8 Sierra 1500 models excluding those with the 6.2L engine.
