No factory torque specs on any Model T fasteners. So just snug them up tight with a 6"-8" long wrench.
If you want to use a fancy torque wrench, this chart works as a guide. The #3254 Magnet bolt is 3/8" dia. Old bolts from those days are grade 2 approx. Specs would be determined by the bolt wear and hole thread condition.
Early ones were wired, later the wire was figured not needed, just wrench tight the bolts.

Re: Torque value for magnet bolts
Didn’t no that about the magnet bolts and whether to wire them or not. I had to think twice about it after seeing this post. The last T I restored was my 21 Touring. I found a correct engine for that year at Chickasha and rebuilt it. It had the magneto bolt wires on and I rewired them after the transmission rebuild.
I have transmissions with bolts with the holes in the magnet bolts with and without the wire. So I guess that would be a way of dating the transmissions. The Ford service manual shows the bolts with no wire in them because the car being worked on in the manual is a 24 or 25 which would be the later transmissions with no wire magnet bolts.
Another time saving effort for Ford. Probably saved about 5 or so minutes, maybe more?
Thanks for my ‘update’ about the bolts! Always learning something about T’s!
