71 Dart get 408/ Trick Flow Heads....

That happened to me a few weeks ago. Lunati locks retainers and springs. Just as YR said.

Had an issue this morning while shimming the valve springs...on the last exhaust valve as the spring was slowly released back up...a valve lock snapped....never in my life have seen this before....these are 7 degree locks....I used a set of comp cams 7 degree lock to replace both of them on that retainer...

Not sure if it is something i did or what?.......
