PUSHROD GUIDEPLATES FOR EDELBROCK HEADS
Made from high-grade alloy steel and hardened to 60 Rockwell “C”. Stepped plates support pushrod closer o rocker, stabilizing pushrods. Set of 8.

REPLACEMENT VALVE SPRING LOCATORS & SEAT CUP KITS
Valve Spring Locators and Valve Spring Seat Cups provide a hardened barrier between the valve springs and aluminum heads, positively locating the base of the spring to prevent unwanted spring movement.

HARDENED STEEL PUSHRODS
For use in engines with or without hardened steel guideplates. Manufactured from case-hardened tubing with a surface hardening and welded ends for maximum durability. 5/16” in diameter, except for #9605, #9635 and #9654 which are 3/8” in diameter. Sold in sets of 16.

REPLACEMENT VALVE SEATS
For use in engines with or without hardened steel guideplates. Manufactured from case-hardened tubing with a surface hardening and welded ends for maximum durability. 5/16” in diameter, except for #9605, #9635 and #9654 which are 3/8” in diameter. Sold in singles unless noted otherwise.
