Looser valves are less likely to burn. Ford increased the exhaust lash to .022" on the 'B' cam.
What does a compression or leakage test show ?
Personally I'd just as soon be able to hear them than not.
You might also want to check the lift on each lobe to see how the camshaft is.
Its a considerable amount of work to make changes which ever way you decide to go.

Patrick,
Clearances, front to rear, are: E1 .018 I1 .014 I2 .016 E2 .018 E3 .020 I3 .015 I4 .016 E4 .018 . Consensus seems to be that this is not too concerning. I think I will hang in there for a while and after the car is finished and I start driving it regularly, see what happens. Maybe with the suggested addition of MMO and a few hundred miles things will improve. I might do a compression test if I can find an adapter for the gauge. This should tell me if valves are sticking?
