For whatever its worth I don't think the extra ten pounds from 90 to 100 is going to matter a whole lot unless you can verify that that value is what was originally used to hone the block. When we check torque wrenches on a strain gauge I see that much variation from tool to tool.

And some of it will depend on the lube used as well. The crush load applied at a given torque value will be increased with each tightening sequence for a few efforts as well as the threads burnish in to each other and friction is reduced.

I would not lose much sleep over it.

I have had customers request that we put a ball bearing in the bottom of each stud hole so that the studs do not bottom out and "cock" on the threads - an interesting idea. I have seen other studs (A1 used in Shelby blocks) that had an extended nose on them to accomplish the same task.
