Thanks!,hopfully this time everything is straight and iv got the correct timing...everything lined up at 20atdc!.

Very Interesting! sounds similar to some of the issues im having with mine:

1-difficult to keep a low idle
2-massive amounts of boost down low
3-power dies rapidly after 6000,but this could be due to not switching of intake advance

Intereseting about tthe AMG cam sprokets,you would possibly have to compare them side by side unless you can find genuine MB/AMG info!.
Its pretty hard to get second hand AMG bits here especially cams etc,im waiting for a C36 rear bumper to finish of my kit,its going to be a while =)
