http://www.summitracing.com/parts/CCA-943-16/ Springs have about 10-15 1/4mile passes on them, where bought new last year, they have been checked after they where removed and spring pressure is still perfect. Also have +.050 10 degree locks,and +.050 Spring Retainers,11/32 valve stem, The springs locks and Spring Retainers, springs where setup on a Solid Roller ,ported stock lt1 head.

This is the origional add that I bought these springs from, and I never installed them or pulled them out of the box I got them in. My build is moving in a different direction, so I'll no longer be needing these. Retainers and locks included

$200 plus shipping. Pics available upon request

Thanks for looking!
