rockers loose?

[aj_tatted]

i slammed a sbc 350 with 882 heads into my truck.
however the problems is,...the rockers keep loosening up.
why would they do that? could it be possibly something to do with the lifters?
i'm afraid that if i have to tighten them one more time i'm really gonna [darn] something up. /forums/images/graemlins/weld.gif

use new rocker nuts and you'll be fine, or use some poly locks for added security! good luck /forums/images/graemlins/waytogo.gif

yep most likely the nuts are just not staying in place, time for new ones and/or new studs too

good luck

Check the studs they may be pulling out of the head if they are not the threaded style.
This will cause the lifters to slack off , be re-tightened until the studs pull out of the heads /forums/images/graemlins/eek.gif
