I doubt very much that Pye fitted matched pairs in the first place so I wouldn't worry.
Early transistors were often supplied in matched pairs because of the wide difference between individual samples but I'm not sure that you will find matched pairs of the more modern types. Valve performance is much more consistent than those early germanium transistors!
If the pair you have are new, that should be sufficient.
Otherwise two valves in similar condition should do the trick - if you've been happy in the past with the 6V6/EL33 mismatch, they can only be an improvement!
