W2 heads on a 318

You are going to have to wind that W2 318 to the moon to realize those heads. build the rods, bolts and cam to suit, I say use the W2 strip dominator and the 5500-8000 range it offers. The Boss 302 was similar, that idle would die if the dome light came on.....I dont think youll need to notch anything, that is 273 stuff.
