I have a set of semi-machined prototype W2 heads that were being advertised as LRT development heads when I bought them. I believe they were shown as such because they still have factory-style heat crossover passages, while W2s never did. Bill Richardson, who worked heavily in the W2 and SCCA programs, identified them as what he called "W1" heads. He said they were originally intended for SCCA cars, even though Chrysler was no longer directly involved. He was also extremely curious as to how I got my hands on them, as "we cast less than 25 sets of those and I'm sure I knew where every single casting went."

Michael @ B3 Racing was a great help in getting them identified. He recommended I leave them alone (as opposed to finishing the machine work and using them) due to their potential historical value. They're currently sitting on a pallet in my basement, not far from where the iron W2 intake normally sits. Prior to learning what those heads were, I had considered building a "what if" LRT W2 engine.

The cast-iron intake was intended for circle-burners with rules requiring an iron "production type" manifold. The W2 spec for the LRT had called for an aluminum Edelbrock intake and a Holley carb, if memory serves.
