I have several Henry's. I always use Warne 2 piece mounts on them. They are very robust, and they are the lowest option available. IME, the Talley 1 piece LW units put a low power scope well suited to levers up higher than need be; further, like others, I've had trouble with the ring tops cracking.
Unless you need it for ring spacing or to add inclination, a rail is just redundant on a solid receiver top design. And while aesthetics are certainly distant to function in the importance hierarchy, to my sensibilities, multi grooved rails just don't look right on a classically styled lever or single shot. I do have Warne 1 piece rails on several 7600's, but they are of the style that only has 2 slots. They are also very low profile.
