I have a set of 241 heads that came off a 2002 Camaro with 60k miles on them. We used the valves in a set of ported LS6 heads we bought as well as the rocker arms and rocker supports. Looking to get $300 + shipping. They will be coming in a head box so they will be safe during shipping. Guessing the total weight is 40lbs and coming frfom 95076 zip code so you can figure out shipping cost.
