2.2 performance valve springs?
Anyone know of a good company that makes aftermarket valve springs? Just curious I am going to be doing a new head build in a bit and want something that will handle the high rev range a little better, I have noticed the stock ones get a little floaty around 6100

I've heard of 2 zzp springs breaking and dropping valves I'll pass on that.
Supertech is very good I have supertech 94lb springs and love them. One of the best springs for the L61 is PSI ML1320s only downside is you need to machine the valve seat to get proper valve spring height. But they are extrmely durable. Also GMR makes a dul valve spring kit that I don't have much info on but the ones that have used it say it works well.

Ecotec forums as well as JBO both of which had springs snap one with supercharger grind and another was on stage ones. My guess was both from the top. My 94lbs are from the top and have been for 2 years no problems.
