I had to disassemble my 3.0 to fix a broken piston ring on #1 from a recent rebuild. I decided to completely disassembled the heads/ housing on the 1,2,3 side. The 4,5,6 side I did not. I pulled the cam housing, heads, cam and rockers as one unit. In building things back up I put the 4,5,6 side back on as one unit with the cam and all the rockers. I have backed out all the valve adjustments except for intake #4. The 1,2,3 side I have installed heads, cam housing, cam and intake rocker #1. No other rockers are on this side. So finally the question. Will I be able to accurately set my cam timing like this? I'm not being lazy, I just don't want to break, loose or damage something removing the remaining rockers from 4,5,6, but I will. Or should I add all the rockers for 1,2,3?
