My early 80s 302 has 1.72 roller rockers. It's not a valve ticking but it makes a small ticking noise. My dad said it was a loose rocker. So since it's had the work to be a roller motor don't I just take the valve covers off and tighten the bolt on the top of the rockers?
Set the piston 1 on TDC a check zero lash on both valves. Then torque the rocker from 19-21 and no more than half of a turn clockwise. Use the firing order to make the process on the others rockers.

If you think it might be an exhaust leak, fasten a small piece of white rag (for better visibility) on the end of a stick or rod of some type and use it to check around the header flanges and other possible leak areas. If the bit of rag flutters around then you have located a leak.
