So What is cam beaken= just means your lifter will turn when ideling. If you have a bent push rod max is like 0.20th's So roll on a talbe top to check or buy new one's there cheap enough. My#1 use was STP for cam & lifter and Cam bearing with a fresh startups with double valve springs,I startup with out the valve covers but a was a bit of a mess tho but,I make sure all push rods were spinning. Then set the hot valve lash running 5 wt
oil back in the good old days. in the 60's, then in late 70's another built hyd lifters v cover off fast ider help 1 or 2 push rods to turn Ok put cover on 30 yrs ago engine 175,000 miles still running but rings getting a little weak on one cyl down is to 90 PSI compression...Aw the good old days
