rocker arm oiling HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

for all of you that want to know what my gain is to convert to full time flow you block off the flow through the cam and that directs that oil to the mains and the 4 rods that see a pressure drop every time the hole in cam line up and at higher rpms that pressure drop is a bad thing and my thing was is to put the restrictor in the deck so I wanted to know a size sense you would have to pull the head to change it but after looking at the problem for little while I found a way around having to put in the deck I was able to put one in the head under rocker shaft so I can just pull rocker to change size plus full roller rocker want more oil to keep the needle bearing alive
