I have no idea how these will work as enlarger lenses, but I use a 150mm f/9 as a taking lens for both 4x5 and 8x10. The 150mm f/9 Hexanon is a dangerously sharp lens as a taking lens. I've used it from infinity down to 1:1, and the lens has never let me down. I have no reason to believe that the lenses you have wouldn't be wonderful as enlarger lenses. (Note: I only shoot B&W; if you're thinking of using the lens to enlarge color than you should seek information from someone who has experience using the lens for color work.)
(My copy of the 150mm just reaches the corners of the 8x10 with usable image; there is literally no room for movements. Reports on the web indicate that some samples of this lens will cover 8x10 while others miss by a little bit. Lens-to-lens variation makes it a crap-shoot as to whether or not the lens you have will cover 8x10 at infinity, but I wouldn't recommend that anyone run out and buy such a lens for 8x10 use unless they were going to be shooting closer than infinity. The chance that a given lens won't cover is just too much of a risk to take, in my book.)
Be well.
