Police Interceptor Heads?

I just talked to Mike about this and he said his dad was a Chrysler engineer, he ordered the truck. He said his dad was working on the Little Red Express project and they had tried the W2 heads on the 360 motor and it was a killer engine. He did say no production 360 engines had the W2 heads from the factory. But his dad had the pull to get them installed on the motor. My mistake saying it was from the factory, but they did!
