$250 for usable Vortec heads(Barely Covers the cost of one)

I would nab it for sure! Adapt the Heads to you current engine(Have a Machine Shop go over them, rebuild them. Also drill steam holes, depending on your Original Block), use a Vortec-style intake, and self-aligning rocker arms.. Should be able to see a 20-40Hp bump from the Stock Heads
