Now, we need to see the next evolution in just the 18* Chrysler head...the W5. It’s not popular, hard to find, most castings are ****, but the W5 is a MASSIVE upgrade over the W2. It takes the same offset intake rocker, but the big improvement is that the intake runner is RAISED. The intake port is something like .750 further off the deck than a W2. Maybe Rumble can measure one for us if he is up to it, as I know he is sitting on some of them. Whatever it is, it he intake is much higher in the W5 than the W2. That is a HUGE deal. Not only do you have all the benefits of the W2, plus you raise the runner. That means the short turn, the short side radius...
