I was thinking of doing the LS3 heads my self but for the added cost and the hp increase in the higher rpm range, it just didn't make sense for my truck. If under the other hand if I was building a 408" stroker then the best bang for the buck heads would be the LS3's all day, especially with the valves now unshrouded. On a different note I have driven a buddy's truck with the LY6, cam and tune and it felt as quick, but not staggeringly quicker than a mutual friends older LQ4 with shaved iron heads and very small cam.
