Holden Red 6 Head is back with new upgrades!

Clarkos Performance has exclusive access to After market holden red cylinder heads



Cast iron XU-1 heads have been fetching a premium on eBay and finally someone has been motivated enough to make new castings. Aussies are world renown for their resourcefulness and Ian “Moo” Moodie is one of our quiet acheivers who grew up under the influence of engine builder Ron Richards at the Brisbane Engine Centre. Just a couple of the customers who “Moo” has ported heads for while at BEC were the XU-1 heads that went onto the late Grenville Anderson’s XU-1 speedway torana as well as the Cleveland heads that went onto Dick Johnson’s blue and green falcons.
Rather than duplicating the XU-1 castings exactly with all their inherent design flaws, “Moo” has improved the head so there is 1/4″ of metal under the water jacket and beside the intake port. The intake ports are modelled after the best flowing red head Ian has ever done. Already there are currently 15 customers waiting (as per March 2009) to hand over $3500 (excl.GST) for the finished heads. Geoff Truscott, who is doing the machine work, is held in high regard by many for his quality workmanship. The heads are cast in Queensland with the factory part number and are indistinguishable from the original.

“Moo” was behind some killer Ultraflow Ford manifolds a few years ago. If you have got a Ford powered by a 250 six, a second-hand Ultraflow manifold is still a magic bit of gear. Locally Brett Mathews uses an Ultraflow manifold with a Steve Gay ported stock valved head in the Outlaw speedway class to lap $20’000 metho burning V8′s. Brett’s cast pistoned 250 bottom end comes from the wreckers and has done about 100’000kms. The Ford six with a Pipemax designed 6 into 1 set of extractors has one of the most unusual, distinctive and beautiful exhaust I have even heard. :D

    I have one of Moo’s ultraflow manifolds to suit a holden six. I managed to buy it off his son Adam. Not sure if there are any others around but i have it in the shed waiting for a project down the track..
