I would think they will work fine... although a tad rougher, with a bit less resolution the a more current servo.. I'm thinking its in the gearing.. I've checked out a few of the older Futaba servos, and have several in my "servo drawer".. and memory tells me... individually they sound good and operate smoothly... but an old model servo against a newer version.. I'm thinking a newer generation servo would win out on smoothness and resolution...
Ya know though... we all used those at some point.. and will again...You'll do fine with them.. . Good luck with it.
