Default VTEC rockers not locking?? video attatched

I've been having issues trying to figure out what is wrong with the vtec on my build. I already made sure that the solenoid clicks and that its getting power when it is supposed to at the engaging rpm.I have neptune and disabled vtec speed check, temp check, pressure check, etc in order for it to come on while I rev the motor. The solenoid gets power so that rules out the wiring and ecu.

Now I decided to do the air pressure check on the vtec rocker assembly and I took a video to get some opinions. With about 55psi of air pressure applied via the access bolt removed on the front of the head, I can press down on the middle vtec rockers and they don't seem to be locking. With the rockers on the base of the cam lobe and air pressure applied, the middle rocker moves seperately from the primary and secondary rockers...on all of them. Am I testing this correctly? The motor shouldn't have to turn over in order for them to lock as long as its on the base circle correct? Video below...

I bought the head as is from someone. Its a possibility that its missing pins I suppose. It should be locking with air pressure correct? Does anyone have a pic of the rockers and pins? 2 pins in each rocker assembly correct? I also notice that when under full throttle my oil pressure fluxuates erraticly which is no bueno. So that leads me to believe that its missing pins and just bleeding off the loil pressure. What you guys think?
