Max lift that LT1 valve springs can handle?
I put stock LT1 valve springs on my heads when I put on my Crane Gold rockers a while back but I dont remember what lift these springs are good till.
I have searched but cant find the answer, does anyone know?

They're at least good until .460", since that's the largest lift on an LT1 cam.
If you click here, you'll see the springs (#98214). According to them, they're good for .510" lift, but that doesn't mean those are the ones you have.
I'd pull one off and check it just to be sure.
