360 rocker ticking

Thanks you guys, first of all I have Mopar Performance covers on. I get 30 to 58 psi on oil pressure. I have a gauge mounted behind the hood scoop, and also Dakota Digital on the dash. They both match psi exactly. My question is can I remove the whole rocker train to check push rods etc.? And replace worn parts easily? I have pictures on my I Pad but can't figure out how to post them in this forum. Also, I have idled this motor with the valve cover off. Is there something I need to look for other than noise? Thanks again!
