Anbody have problems with Hughes rockers loosening?

LA or Magnim set up?

I have a 410 Stroker that is LA RHS HEADED and I take it to 7k all the time. I have Hughes Rockers and billet hold down shafts. They NEVER have come loose. Just tonight I put over 100 miles on it and Ran the piss out of it when I got to my destination Running through ALL the gears MANY MANY times with 4spd and 3.55 gears shifting at 6800-7000 RPM and then drove it home 50 Miles when I was done! Runs like a CHAMP!

I seriously believe you did not tighten them up enough.
