Best Spring For .612 Lift Cams??

Ok so to make a long story short, a while back my Crower valve spring broke and ruined some stuff on my engine. I called them, they never called me back. I've talked to several different places, and have yet to find a spring that can handle that kind of lift with the exception for the Crower's. Well, I really don't want to go back to Crower springs for 1. the damn thing broke the first time, why would I trust them again, and 2. they didn't even have the courtesy to call me back to explain what may have went wrong or to investigate the problem. So...ANYONE got suggestions/ideas? I'm trying to have the car back together in 2-3 weeks so...any help at all would be great!!
 
well I would call

vt engines
MPH
fox lake

a few places that biuld insane cars and see what they say. I don't think the comp springs are good to .612 and that is what most places use.

shoot a pm to cobrakiller (mph) see if he as any suggestions.

you could alwasy ebay the cams and have some custom vt or comps ground

were the crower's off the shelf or custom? If they were off the shelf I would use this as a chance to get a custom grind. the articles I have seen on the crower cams they did not produce as good of power as vt or comp.
