yeah i looked at them before i don't know if i want to spend 1000 plus on my heads right now. lt4 cam setup is 5something machine work would be about 100-150 being that my good friend is an owner of a machine shop. i am still leaning on getting another set of stock heads for like 100-150 cam kit for lets say 550, and machine work 100 so that would put me at 800, so i guess i can consider the le1 heads. we shall see
