Better a V8 than a whipper snipper.

Anyone agree? 🙌😂

A few shots of Rob Walden’s weapon after taking out the 2025 Super Stock Championship with the Southeast Gassers Association.

Rob and the Walden family have been part of the Yella Terra journey for a long time, building serious cars and pushing them hard where it matters most, at the track.

This one means a little more. While Lamar Walden is no longer with us, Rob continues carrying the family name with pride, passion, and the same dedication to performance that built the reputation behind these cars in the first place.

That’s what real Australian and American performance culture has always been about. Family, legacy, hard racing, and keeping the next generation moving forward.

Congratulations to Rob on an incredible achievement and for continuing to honour the Walden name the right way.

Track tested. Street proven. Trusted for generations.

Ever wondered what separates a great build from a legendary one?

It starts here, on the factory floor. This is a behind-the-scenes look at how Yella Terra roller rockers are precision-manufactured right here in Australia. Every component, every tolerance, every finish. Built to perform under pressure.

If your engine is your pride, the valve train is its heartbeat. And we don't cut corners on heartbeats.

DM us to find the right roller rocker for your build. 🔥

If you're building a serious Holden 253 or 308 carby engine, the Yella Terra DASH-3 Assembled Hi-Port Cylinder Heads (P/No. ABHA 308-3) are the most complete power upgrade you can bolt on.

These fully assembled alloy heads feature a raised intake port design that improves as-cast airflow by up to 40% over standard factory castings, and they support 490+ horsepower straight out of the box. Specialist head porters can push airflow to 260 CFM for even more power, thanks to redesigned water jackets that leave plenty of material to work with.

At 50% lighter than cast iron, they drop massive weight off the front axle and improve throttle response too.

Each pair comes ready to install with 21-4N stainless steel valves (1.940" intake / 1.600" exhaust), high-lift double springs, and chrome moly retainers. Machined for 7/16" UNC threads to suit screw-in studs or Yella Terra's own shaft rocker systems.

Proudly Australian. Seriously engineered.

Before the CNC machines, before social media, before the billet era… this was where it started.

An HR Holden 186S being tuned back in the 1960s inside the original Perfectune workshop, the business that would eventually become Yella Terra.

The second photo says it all. Original Perfectune advertising from 1969, promoting modified cylinder heads for Holden sixes, V8s, towing, street performance, and racing applications. Long before aftermarket performance became mainstream in Australia, these guys were already building engine packages and testing combinations in the real world.

Back then, performance wasn’t bought in a box. Engines were developed through testing, racing, trial and error, and long nights in the workshop chasing every bit of horsepower possible from Holden sixes and Aussie V8s.

What’s even better is that those original workshop photos hanging on the wall are still with us today inside the current factory. A reminder that while technology has changed, the passion for Australian performance engineering never left.

More than 60 years later, the same mindset still drives everything we build. Real parts, tested properly, built for people who actually use them.

Track tested. Street proven. Trusted for generations.

Who remembers the Perfectune days?
Or had a Yella Terra equipped car back in the day?

Is your Holden 253 or 308 V8 is still running factory stamped steel rockers? Yes? So you are leaving performance on the table!!!

The Yella Terra Pro Street 1.65 Shaft Mount Roller Rockers are engineered for serious street/strip use. Rated to 600 lbs open spring pressure, built from aircraft-grade extruded aluminium, and sharing hardware with our Platinum race series. The shaft-mount design doubles footprint and clamp load for serious valvetrain stability, while precision-ground trunnions and oversize needle bearings keep friction to a minimum.

Best part? True bolt-on fitment onto original mounting holes, no cylinder head modification required.

Compatible with Holden 253 & 308 V8 factory heads (1969–1988) and Holden V8 304/355 VN PFI engines.

Manufactured and assembled right here in Australia.
