This is cool! never new it... W2 police

I have actually only seen one engine. Saw it several years ago in Alabama (greazy, obviously out of a car, thermoquad carb, dual snorkel air filter, stock type exhaust manifolds, hydraulic cam, non bushed adjustable rockers, short valves). The guy told me it came out of a Texas Highway Patrol pursuit car. Apparently Texas and Arizona purchased several for special duty.

I was trying to help some local Mopar racers get the W2 head approved for the Bomber class. Wrote to Dick Maxwell at Mopar asking about the engine. Got a response from an assistant. The letter confirmed there were some built as special order in late 70s and early 80s. I may have the letter around here, haven't seen it in some time. Something like 350 (memory may be bad) cars were equipped with W2s.

That engine I did the oiling modifications to (pictures were posted) had a set of early W2s like the ones I saw. And the heads came out of Texas about 10 years ago (along with about 10 other sets). The heads had been updated with long valves, pedestal rocker arm stands, etc. But the heads had only the exhaust bolt pattern of the stock X or J heads, not the dual pattern of other W2s (aftermarket) I have seen.

Unless there is a special reason you want the early heads I wouldn't get real excited about trying to find those heads. I suspect someone is ten years ahead of you finding the heads and the later heads are really better flow wise and have a better combustion chamber.

And, unless you really knew what to look for, the engine would look like any other 360.

There are several Moparchat contributors from Texas and Arizona, maybe they can shed some light on the subject; OR, maybe they want to keep it quiet!
