adjustable rockers

First of all I'm glad I'm able to get back in here! After they changed the layout I couldn't get in, it would lock up? I've got a 72 Satellite with a 400. It runs great it is built but to what extent I don't know. I know it's got a purple cam(don't know specs) nice rumble. When I pulled the intake and valve covers to change them (Eddy RPM with 750 1407 carb and Mopar perf covers) I was surprized to see adjustable rockers. Now for my question. I have noticed a slight tick on number 7, everything seems good. Should I just tweak the nut a little on both or what? I have never work on adjustables before. It does have hyd lifters. THANKS in ADVANCE HOWARD!!
