School me on W2 heads.

I could have bought a set of bare W2's for $300 decades ago, the rocker gear was still more than the heads. W2 intakes are out there cheap used, usually Strip Dominators. I actually traded the W2 intake I had for sale to the W2 guy for a LA strip Dominator he had AND a Performer. Good stuff, them W2's. I heard a story that they were made for the kit car race program and even the Warlock/Express truck was supposed to get them. Imagine that truck with stock W2's...
