HOLDEN EFI 304 V8 PLATINUM 1.75 SHFT MNT 7/16" SUITS EDELBROCK PERFORMER RPM HEADS

 Designed for Strength. Built to Race.

No other rocker system compares with the Yella Terra Platinum Race Series.

Manufactured and assembled in Australia using the highest quality materials and componentry — sourced both locally and from the USA — this system is engineered for strength, endurance, and performance beyond the chequered flag.

Designed exclusively for the Edelbrock #61385 Performer RPM cylinder head, this Platinum Series Adjustable Roller Rocker Kit is the ultimate valvetrain upgrade for serious Holden V8 performance builds.

Purpose-built for aftermarket Holden VN 5.0L EFI engines (Edelbrock heads only) – these rockers will not fit factory VN 5.0L iron heads.

Why Choose Platinum?

• Wide body arms deliver exceptional strength and resistance to deflection

• Extruded from aircraft-grade alloy for high RPM potential and heat dissipation

• Built to withstand over 900 lbs of max open spring pressure

• Oversize full-complement caged bearings designed for oscillating (rocking) loads

• Precision-ground oversized shafts minimize friction and enhance durability

• CNC billet arms meticulously balanced for valvetrain harmony and stability

• Proven bolt-on shaft mount design – mounts inlet and exhaust to a common shaft, doubling footprint and clamp load without head modification

• Various ratios available to complement any camshaft grind

• Chrome moly steel hardened roller tips (positively retained with internal circlip) prevent valve tip abrasion, reduce wear, and ensure quieter operation

Race-Proven Platinum Series Engineering

The Platinum Series represents the peak of Yella Terra’s racing innovation.

Each system is FEA-engineered, precision CNC-machined, and rigorously tested in Australia to deliver unmatched strength and valvetrain stability under extreme conditions.

Built from aircraft-grade aluminium extrusions, this kit can handle 900+ lbs of open spring pressure — ideal for high-revving, competition-level engines.

Our wide range of true rocker ratios allows you to achieve higher valve lift without overly aggressive camshaft profiles, reducing valvetrain stress and improving reliability — a technique now widely adopted by professional engine builders and racers.
