Hi.
I think the OP has answered his own question in the last few posts.
Fitting an 8 ohm speaker of dubious efficiency is the crux of the matter. If you need to crank up the volume to get a reasonable sound you could well be driving the amp too hard.
If the original 16 ohm speaker was efficient and required less drive for the same volume than the 8 ohm replacement then I'd say that it would be an idea to revert to the specified speaker.
Adding a matching transformer could be a safeguard or an idea if a good quality high efficiency 8 ohm speaker is available.
