Tight valves are more of a problem than loose ones...
if they're loose then they close early an open late ... It rattles a bit a looses some performance - no harm done.
if they're tight then they close late (or not at all) ... The result can be burnt valve seats and even 'blowback' through the carbs.
Blowback is highly amusing (and destructive!) and involves smoke and flame emerging from your air-filter :eek
Yours sound tight ... I'd measure them again... They don't usually go tight, apparently.
