I was confused at first but after some digging I realized that you plan to plug the head.
I'm running the RB PVC valve + BMS OCC. I see that these are on the high pressure side only. Here some videos so we're on the same page...
pvc install
occ install
But we didn't do the external version w/ the plugged head...
The d.y.i. I read up...
