Just fully rebuilt a 81 22r and set valves way off till yall helped me but now I got them on 8 and 12 thousands but they still rattle when motor is pulling. Can't hear them when at idle. Buddy of mine said it could be the rocker arm assembly could have weak springs and letting the rockers smack back and forth....I don't know what to do HELP HELP

yoterr
