Rocker arm hex locker

well, i am trying to adjust all my arms and realize that i am missing on of those hex head lockers you spin in last. Would it be safe just to go ahead and put a lot of thread locker in the main bolt thing and give it an extra turn or so?
 
HELL NO!

whats more expensive, 2000 dollars in the upper end or 50 cents for a set screw? I know its tempting to get it all together man im in your boat, I am doing a headswap too but keep your attention to detail or it'll bite you on the ass down the line.
 
well, i went to ace Hardware and they didnt have it. I called up the local speedshop (1/2 hour away) and they told me they might have one laying around and to bring one in a match it up. Well, i got there and they found one for me. the Heads, rockers, intake is on. Pretty much just left w/ a few misc things in the engine and the fuel pump
