Has anyone on the forum used PSI valve springs and the LS1511 in particular? I am particularly interested in the longevity of the spring.

Iirc Wegner uses them for their nascar engines. They are a very durable long lasting spring.

I use 'em on just about everything than doesnt warrant a dual. very good spring for the price. they do have enough pressure to need good pushrods and timing chain though.

I have them in my car currently, been in there for 30k already. But i have a mild Cam Motion cam that not really all that aggressive. I have yet to check the spring pressures on them since they've been installed. Planning on doing that this fall but Im not worried really.
