so when advancing the cam do you move it clockwise or anit-clockwise? and does advancing it improve top end or bottom end? cheers.

See my bit above repeated below:
General rule re valve timing:
Advanced valve timing favours low speed running.
Retarded valve timing favours the top end. This applys to single camshaft engines. The retarded timing gives a later closing of the inlet valve which allows for air flow lag at high speed.

Advancing the cam would be going backwards in my opinion, Maybe this whole theory is upside down and Holden infact allready advanced it? that would make more sense. If you retarded the cam and advanced the timing to make up for the loss in bottom end, then you would be going places
