Tom responded that it shouldn't be a problem and that there is plenty of threads. I do understand what you are saying though. Does anyone know of an actual spec for how much thread engagement rocker arm locks need? It's a 1" long nut with a roughly 3/8" lock inside. Some of the videos I've watched on valvetrain geometry seem to have their locks down inside of the nut a ways as well. Maybe I'm freaking out over nothing.
