using a jamb nut for rocker adjustment nuts

To prevent my rocker adjusting nuts from backing off, can i use a jamb nut that will stop the other from backing off? What grade of nut would i need? i'm guessing grade 8?

Thanks for the help

I just go to the junk yard and find a "virgin" engine, or one that`s never been stripped down, I snatch the rocker nuts off them and in every case so far it solved the problem.

My son used jam nuts on his Ford rockers as an emergency measure. As far as I know they're still there w/o a problem.

I would think grade 5 nuts would be adequate. Grade 8 is probably an overkill, but if you'd feel safer, do it.

If you need to use a hard nut, use a connecting rod stud nut. Actually, any grade 5 or better nut will work fine. I'm using the same system on my 350 right now. Works fine and is cheap!
