Holden V8 Roller Rockers — CRHL8167

A stainless-steel rocker set for Holden 253–308 and 304 engines with VN heads. The specified ratio is 1.65:1 and the stud size is 7/16 inch; poly locks are included.

The stud-mounted arrangement needs studs, guide plates and cylinder-head machining. Crow explicitly excludes solid roller cam applications from this rocker’s fitment.

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 Commodore VN–VR — 5.0L EFI V8
Holden Commodore VS — 5.0L EFI V8
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

Verify rocker ratio, stud size, pushrod length, guide-plate alignment, sweep across the valve tip and poly-lock clearance before final assembly. Confirm the rocker is approved for the selected cam/lifter type.

Ordering and BBT support

Built by Boost & Tune can help confirm the correct Crow camshaft, springs, retainers, locks, lifters, rockers, timing components and supporting hardware as one compatible package. For modified cylinder heads, non-standard valves or an unknown existing combination, provide the engine specification and measured valvetrain details before ordering.
