I hate to say it but it seems you are confused about a whole lot of this. and more.
The 177 is not stripped. Most roots blowers are not stripped.
Stripping the rotors is a way to recover-restore the blower case to rotor clearance on a rebuilt 671 blower. That re uses the remachined case and rotors.
Usually only used on a competition purpose 671-8-71 blower.
I suggest you download and read the technical-instruction manual on Roots superchargers, on the Holley/Weiand site.
The hows and whys are covered.
