Am I right in thinking these are the highest performance OEM cams used in the KZ/GPZ range ? would like a set but they are like "hens teeth"

I do believe so...

My interpretation: 



300 Uni-Trak degree duration vs. 270 KZ, ZN, etc. other J's

See:
Stock J-model cam options? - KZRider Forum - KZRider, KZ, Z1 & Z Motorcycle Enthusiast's Forum

That's really interesting Dave, my stock "K" cams have a height of 36.0 where as the"J" has 36.9 on the inlet and 36.5 on the exhaust. I have managed to find a pair of "J" inlets so 36.9 on both which appears to put them in the middle of your stock 1100 and your "Uni" cams so should at least give me back what KHI took away for the "K"

Yes! highest stock lift of the big aircooled fours.
I have a set for my turbo, they measure 9.7mm lift.
There's a set over on the UK Z1 owners site for £250.

Looks like longer duration too.

Indeed I believe around 300

Thanks for the "heads up" Rob. The deal is done and I will be collecting early next week 

Hey Wookie58, Congratulations on your find!

Tried to view the cam pictures on the Z1 owners club forum post but wasn't granted access.

Please repost them here and we'll gloat  celebrate over them with you.

The camshaft sprockets




...are different



too

Dave you're naughty   the angle of the picture is different (I've never seen a sprocket where the mountings are not on the centre axis unless there is three bolts) have these cams previously been run as a conversion in an earlier engine (left one is marked up as Z1000)
