Hi Jamie,
What are the ATDC maximum lift figures in these two cases? the reason people don't usually time camshafts off opening and closing figures is that the maximum opening figure is easier to get accurate/consistent results from.

Running the cam advanced will lose top end power without picking up anything you'd notice @ low RPM. Running the cam slightly retarded -not as much as 10 degrees, gives good top end power, but the low down power loss is likely to be noticeable in a heavier car. As the old engine builder saying goes, 'with cam timing as with a pub, late closing is always better than early opening'
