I have LS1 heads that were hand ported. I ran them on my old motor. With a baby cam (224 duration and a 585 lift) they made 370-372 rwhp through an auto with an unlocked converter. i never got any track passes with them. They are bare heads but i believe i have the valves for them. I am asking $250. I do not have any flow numbers. If you are interested feel free to PM me. Thank you.

 

bump for me

 

up for me and a good set of heads
