The scenario is this :-
I have a V12 cylinder head. Both the Intake and exhaust sides of the head are twin valve. Therefore I have 12 valve stem tops to 'cam-mate' to the respective camshaft lobes. My question is, is it better to finalise each and every 'cam-mate' (per lobe that is) or is it better to mate all of the valves stems to respective lobes for the entire camshaft and then finalise it? Or............. does it make no difference either way? In my way of thinking I end up with the same amount of mates either way but I want to keep rebuild times to a minimum and therefore wondered if one process might be better than the other.
