Yea I wouldn't start the engine before that's fixed. I assume you have some significant seat pressure with the engine being setup for boost and might have led to the fracture you see. I would hope the ultra mags won't have any issues....mainly because I have them on my new build lol. Good thing you caught it before it became a big problem.
But seriously like everyone has said, aluminum SUCKS for rocker arms.

Spoke to some other folks about this and said that this basically could be the result of coil bind. But after talking to the builder of the engine, he ruled that out altogether. Tend to believe him, as this is a clone engine and that engine has been running strong for the last 9 yrs.

You know, I've been aware of that since those suckers were released. But from what I can tell they had a series of bad batches but it was so wide spread, most people simply switch over to beehives or patriot springs etc. I'll replace the rockers and see how things go but in some regard it's silly to do that and not change the springs while in there to begin w/.
