I am starting a 318 magnum build myself. Got it for nothing about the worth of it. So I'm buying heads, crank, rods and roller lifters. I'm still not sure what I'm going to use either. Thinking about EQ heads but Speedmaster has aluminum assembled heads I found on Ebay for $ 1015. I'm considering the aluminum heads just cause aluminum is much easier to port. Scat has some really good stuff and prices. So keep in touch and maybe we can be of help to each other.
