Drag Racing Tech - GZ LSX Vaccum pump need help pls!!!

hi
as title say just thinking to buy GZ oil vaccum pump but wondering
about which one to go with !!!! , and what will i do with stock PCV port from the Valley cover !!!! and where to fix the vaccum gauge ? :bang:
any one did this befor ? need help with this pls ( post pic )

I am running their VP101A pump currently pulling around 11in. On the valve cover deal I'm not sure as I am running aftermarket valve covers but I imagine you can put a breather in it. I just drilled and tapped the valley cover for the gauge.
