I've got a June 2001 AU2 XR8 which I believe to the 200Kw version. I had look at my roller rockers the other day and found they were Yella Terras. I thought the 200kw engine had ford roller rockers. Have had a good look at the TB and there is no Tickford stamp on it as per the 220kw cars, am pretty confused. Is there any way of telling what ratio they are because I want to install a crane cam, but don't know which grind to get til I know what rockers I've got.
Any help would be much appreciated.

I had the same issue when selecting my cam, the rockers should have a number 6 or 7 stamped on the nose of them(1.6 or 1.72 ratio) if there is nothing there they are most likely 1.72, I phoned yella terra and asked them and they told me the only rockers that left their factory with no markings on them were the factory fitted 1.72 ratio as fitted to late AU V8's, hope that's of some help
