Rockers are "ticking" me off

[moonenn3186]

Sorry for the pun. . .

I recently installed Trick Flow heads on a 89 5.0. I am using 6.70 TFS pushrods. I am using a B-Cam with stock lifters and 1.7 roller rockers. My problem:

I adjust the rockers like I always have - exhaust begins to open adjust intake, intake almost closed adjust exhaust - 3/4 turn past zero lash. However this combo seems to loosen itself as soon as I rotate the engine by hand. THey are snug when I set the poly lock - but seem to loosen up right away - all of them!

Any help?

If they are loosening yu can try this trick - I haven't needed to do this yet myself, but others have done this - instead of tightening 3/4 of a turn and then tightening the lock nut, go 1/2 a turn, then tighten the lock nut, and then turn the rocker nut the last 1/4 turn with the lock nut tight - this will keep the lock nut on tight.
