Update...just been over to my mate's house and a couple of other bits of information.

1 - Banana Grooved shafts are already fitted.
2 - The shafts are off a std set of heads and the hold down bolt holes have been "ovalled out" on a mill to fit the offset of the W2 rocker stands.
3 - The oil on most rockers "dribbles" out as opposed to "squirting". I'm not sure what the normal flow out of these would be but I would think that there should be some velocity so the oil reaches the ball and cup.
4 - Rocker gear is the blue anodised Mopar gear. Interestingly, even though it was purchased as a set, there is a distinct colour difference between the intake and exhaust rockers. Not sure whether this is normal or not, but cant see it being a huge problem.

I took a couple of photo's on my phone but dont have the cable to download at the moment. will do tomorrow (AU time).

Thanks for your comments so far!
