Having had several car cylinder heads overhauled by Paul Gilbert since being in Australia, I knew the service and quality was exceptional. That's no bull, they come back like a new part, and I was pretty amazed — especially for the cost.
So when I needed a couple of shims machined on the GS550, I dropped in to see if he could do them. No problem he says, come back in a couple of hours and they'll be ready to go.
Once we got talking I realised he did a lot of motorcycle work too, and he showed me some of the heads he was currently working on.
This is one of two Rocket III heads that were being ported, one for a supercharger. He said that although he has a flow bench, the ports are now so big on this 2.3L engine that he's had to use someone else's larger version to check the flow. That's going to be one quick Trumpet!
