LOL. Just write the number combos down and tick them off as you go. It's a good idea to measure the gaps and write them down before you adjust that valve. You may not need to do it, especially the inlet ones. Seat recession on the exhaust side will reduce the clearance and measuring the clearance before hand will give you a warning that this is happening.
Even with new valves and lead free seats this is still a good habit to get into.
A tip: If you take off the rocker gear, put an accurate straight edge along the top of the valve tips. In theory they should all touch the straight edge with no clearance. Small discrepancies are why you are adjusting the clearances. However. if any of the exhaust valves are obviously higher you are likely suffering seat recession on those valves. Monitor or remedy, your choice.
