Adjusting Rocker Arms on 351C-4V

[dbdragracing]

I have a '70 Mach 1 with a 351C-4V and have noticed a little tapping on the passenger side from just under the valve cover. A guy that is big on muscle cars told me it was a rocker arm tapping and to tighten it down. Do I just tighten the bolt in the center of the rocker down (I already have the valve cover off)..how much do I tighten it? I really need help because we are having a car show and cruise tomorrow at noon. Thanks for ANY help!

There is no adjustment. Torque the hold down bolt to 25 ft/lbs. If you still have a lifter tapping, the pushrod or lifter and/or the pushrods are worn.

Cool...so we are talking about the bolt in the middle of the rocker? Thanks.

Yea, that's the only one. They're pedestal mount rockers similar to the 77-2001 5.0's. Non adjustable.
