Perhaps I misunderstood what you meant.
Of interest, at least 6/16 of mine have been in the engine since it was built, and may still be doing just fine AFAIK, until I next pull the cam cover to find out.

Thanks Chris, but can't you just type/post who does them, rather than making me wait 3 months and travel ~400km to see you? I understand that a number of cam manufacturers are willing to do custom grinds, e.g. Tighe, but it is nice to be able to pick a grind they have already thought about and done before. BTW, my engine builder was not helpful in suggesting cam providers I didn't already know about.

You can buy directly from them. Pay with paypal. Shipping using EMS. I brought some camshafts from them long ago.

I should also add 'B6'. Sorry I didn't state this.

Cat cams make high lift less overlap for BP's. Distributed in Australia by Competition Systems out of Victoria.

Kelford
Keegan
949 Racing
Integral / Webcam
Deckspeed (Daniel has a special grind that we have had success with)
Jesse Prather
Maruha
Rebello Racing

Most of these are o/s but apart from Deckspeed, you have some other Aussie options - I know Gary Stewart has a good grind that produces big numbers in the high rev range. Automotive Plus have seemingly figured it out too - not sure if they are running a proprietary grind or sourcing cams from elsewhere...

Mania have sourced good cams in the past as well, though I'm not sure where they came from.

I have left out Tighe, Toda, and a couple of others who tend (in my understanding) to make less aggressive, more street–focused cams. Perhaps I'm being unfair...
