85mm 12.5.1 CR on GSR Head

Is there anything that needs to be done for it to work properly like open up the chambers or can it be setup with stock chambers?

you'll need to enlarge the combustion chambers to 85mm diameter

It will work with stock chambers. Opening them up will create more volume, thus losing compression.
