40 inch pounds of torque on the front doesn't seem unreasonable, but I'm going to have to back up the recommendation to play with the screws and test for movement or springing. It was probably "farmer tight" up front for K-98s and about half that for the rear tang, which in turn was SUPPOSED to contact a metal sleeve around the rear action screw (to avoid crushing the laminated wood).
What I would want to feel is both action screws snugging up quickly to a firm stop that tells me the wood isn't soft or damaged. If it takes a couple of turns to go from "free" to "tight," it's smart to take a scratch awl or something and see how hard the support wood in the stock still is. If it's gooey or smushed, a bedding job with modern epoxy is in the cards.
