Crow Cams Holden V8 253-308 Guide Plates
Holden V8 253-308 Guide Plates — GP308
Eight guide plates for early-head Holden 253–308 engines using 5/16-inch pushrods. They are intended for the corresponding stud-mounted roller-rocker conversion.
The early-head application is distinct from GP304, which is listed for the VN EFI head arrangement.
Applications and compatibility
This part is listed for the following engine and vehicle applications where the Crow camshaft or valvetrain package calls for this exact part number:
- Holden Torana LH–UC — V8 applications
Compatibility is still determined by the complete cylinder-head and camshaft combination; vehicle model alone is not a substitute for checking the required spring, retainer, lock, lifter and rocker setup.
Installation checks
Confirm pushrod diameter, stud size, rocker geometry and cylinder-head machining before installation. Align every guide plate so the rocker tip remains correctly positioned on the valve throughout the lift cycle.
