All of the aftermarket cams have more lift and more aggressive ramp rates than the stock cams in LS-1s. As lift increases and ramp rates get more aggressive valve-spring stress increases exponentially. If you run a healty cam on stock valvesprings they will break.

How'd you replace them? Just happen to be carrying spares, valvspring tool & compressor? That SUCKS!

I've read about the dual-springs in the OEM spring pocket breaking too. I have no faith in any of them.

Just removing the valve covers and inspecting them, or do the springs have to be remove from the engine?

The key to spring longevity is warm up. Let the springs warm up to engine temp slowly. Too many people leave their house and a block away are already at WOT.
