Is it ok to copy a W5 head and make it better or are we just mad at Speedmaster

I think W2's would be a hot ticket. What makes a W2 a W2 though? What do they say, you have to change 5 things to reapply for a patent?

The fact that it's the only large oval-port head for SBM's, with the Indycar project maybe the only exception, but also had more than one incarnation.
There may be 5 things one could change that are beneficial, but Mopar abandoned it for the successive W designs for a reason, an Al-U-minimum version with closed chambers would rock tho'.
