GMPP dual valve springs for LT1, up to .560 lift 330585-these are the GMPP dual valve springs good for up to .560 lift i beleive. i got them from a guy who had them with a hotcam i think it was, then he stepped up to a bigger cam, and i intended to use them but i got an amazing deal on a cam that is too big to use these with. my loss is your gain.
also come with retainers matched....

they have a few hundred miles on them and were only pulled off to upgrade like stated. 90 bucks shipped.

im sure they could fit most v8s with the proper retainers. best bet is to call GM or a performance shop/machine shop. i know for sure they work on LT1s, other than that, i cant tell ya.
