Hi everyone, we’re chasing a few sets of LS square port heads in good condition to keep our exchange program moving!

With more orders coming in, we need extra sets on the shelf so we can keep up with demand and get customers sorted sooner.

All heads will be thoroughly inspected using the same checks we carry out on customers’ exchange heads.

Got a set you’re looking to sell? Message us or call the shop on 9746 6656.

If you’re a workshop with a heap of heads sitting around, we’d love to hear from you!

We’ll be closed tomorrow as the GMMotorsport team heads to Elmore for the Test & Tune day!

We apologise for any inconvenience and appreciate your understanding. We’ll be back to normal trading the following day.

We are looking forward to welcoming the V8 Superboats tomorrow (for one day only) at the Elmore Field Days.

We’re firing up the BRAND NEW Elmore jet boat track for a special TEST N TUNE DISPLAY — and giving you a taste of what’s coming when V8 Superboats return to race at Elmore! 🔥
