Type 99's have an index mark and you need to align the barrel index mark with the receiver index mark. Once aligned you will need to head space the bolt.
As tight as you can get them with a good fitting screw driver by hand . Get both screws in and just touching . bang the gun down on the buttplate muzzle up a few times . Tighten the forward screw first . Mark 1 - Please tell me how you change the headspace on the rifle after the barrel is installed to the index mark ?
You need to CHECK the head space every time you change the barrel or bolt.
If the barrel does not head space you may need to chamber ream barrel to achieve the correct head spacing. Or try different bolts.

Except the OP didn't ask about torquing a barrel, he asked how much torque the action requires. And though that question has already been answered I'll offer that those rifles and actions were never torqued. They were tightened by hand with a screw driver and made real snug. Nothing more.
"You are what you do when it counts."
I usually start at 25ip and work up to a max of 35ip for non-pillar bedded rifles. After I find the sweet spot, a drop of blue thread locker to hold them in place.
With about 80 years of stock shrinkage the old marks will not matter any more . If you do not get them tight you can crack a stock with recoil . Just look at all the tang cracked Mausers out there due to people trying to use the locking screws , incorrectly .
Thanks to you all for the advice given. I’ll use the advice and apply it to my rifles.
