Roller Rockers came loose
After about 500 miles on engine, some of the rockers came loose. What could be the cause of this.
Valvetrain:
1.6 Comp Pro Mag full rollers NSA
8019 springs from AFR on AFR 1039's w/titanium retainers
AFR guideplates
7.2 Trickflow chromeoly pushrods
Piston to Valve clearance was checked and was ok
Is there any other info you would need to possibly make any suggestions, other than just going through and resetting them all.

If you are tightening the poly locks according to the instructions that might be your problem. I had the same problem. Once you tighten down the set screw give everything another 1/16 turn just to make sure everything is tight. works for me

If you over tightened them the nut may have cracked. Especially with 7/16 studs as the Comp nuts are very thin and brittle. I've broke several before and didn't feel I tightened them down all that tight, but I guess when they get up to op temp they stretch more and start to crack after a few hundred miles. As mentioned, go only 20-25ft/lbs at the most with them.
I started using ARP poly locks since just for extra POM.
