valve springs - recommendations

I ran the p5007548 mopar cam in a stock 5.2 with stock springs. It had .490-.496 lift something like 218 @ .050 duration. Stock keg intake bored throttle body, tuned hooker headers, and a mopar pcm. That was one mean teen!!! The stock valve springs held up fine in it. Ran 8.80 8th miles with severe traction problems could never get it to hook up. And it weighed in 3700# range
