On most every head I've pulled for valve problems the seats and valve edges were worn. In some the valve edges were so worn they looked like a knife edge and little to no seats left. Bottom line, valves need to be checked at the proper intervals and the proper lash maintained. On IC equipment I work on, compression checks and valve adjustments are part of the pm service.
And your conclusion is????
