how much

Using the stock valve springs, how much lift could they handle?
I'm looking at a .449/.475 lift cam.

Contact the manufacturer of the cam, they'll tell you if stock springs will work or not.

And if they will work with that came buy new ones, don't re-use the old ones.

Good point!! And X2 with what Harte and AB said as well. Every cam co. has requirements for how much psi they require of v.springs for each cam. If you ignore that, you're asking for things to go sideways, usually at high rpm's. That is seldom pretty.
