PROFORM’S NEW TWO-PIECE SMALL-BLOCK VALVE COVERS
The Bow-Tie and Chevrolet emblems are displayed in relief within a machined looking background panel. The diagonal angle of the top section ensures no oil mess while adjusting your valves or inspecting your valve train with the engine running. The 2-piece separation gaskets provide a leak tight seal, and there is no need to risk damaging your cork valve cover gasket.
These attractive and handy die-cast aluminum covers allow for the use of larger roller rockers or stud girdles, and they are fitted with oversize bolt heads for easy removal. They also are equipped with a removable OEM style baffle and grommets. Proform two-piece valve covers come with the required Allen wrench, and will fit all 1958 to 1986 small-block Chevy engines. A two-piece replacement gasket kit is available.

L92 Shaft Rockers from JESEL
The only component lacking for the L92 head was a race-ready performance valvetrain. JESEL solved that problem with a sophisticated shaft rocker system that is capable of delivering more power due to greatly reducing valvetrain friction, and providing rock-steady valvetrain stability at extreme rpm.
Much of the friction reduction is due to the 1.400” pivot length that reduces “scrub” between the rocker and valve tip. The rockers ride on precision needle bearings plus a .250”-wide needle bearing nose roller ensure smooth rocker action throughout the lift curve. Other standard features include JESEL’s proprietary 7000 series alloy rocker bodies CNC machined to JESEL’s exclusive Mohawk shape that provides the lightest and stiffest rocker possible. The rocker bodies also featured profiled tail sections for valve cover clearance and are shotpeened for added strength.
Installation is a simple bolt-on operation with no cylinder head machining required. However, taller valve covers or valve cover spacers are required for adequate clearance. For more information, contact JESEL on the web at www.jesel.com.
