Shauns Custom Alloy Holden 304 Valve Covers – Billet Big Rockers

These Shaun’s Custom Alloy Billet Valve Covers are designed specifically to suit Holden 304 V8 engines with VN-style cylinder heads. Proudly machined in Australia from aerospace-grade 6061-T6 aluminium, they offer precision, performance, and an elite engine bay finish.

Each pair is CNC machined using 5-axis equipment for perfect accuracy and fitment. The low-profile design provides clearance for oversized aftermarket rocker gear, while AN-12 breather ports located at the front of each cover make plumbing simple and clean.
