Dialing In The 308's Cam Reveals Timing Troubles

It was going to be a simple learning exercise, to dial in the cam and test the piston to valve clearance of my 308, before starting assembly. But just as well we did it, because dialing in the cam showed up a problem with timing... instead of being 2 degrees advanced, as per the cam's grind, we found 5 extra degrees advance. Where it that extra 5 degrees come from?
