I believe that the original concern was that the 3.0 heads did not have the Contour type water pump drive. That seems to be changed now that the 2001 Taurus/Sable/Escape now have the same water pump drive off the back of the front head.
In my earlier hot rod days we went to great lengths to start with the heads with the biggest valves and ports. I'm sure this hasn't changed.
Now if there was just an easy source of the other things such as forged pistons, forged rods, greater cam selection, alternative intake manifold designs, etc. etc. etc.
It would also be nice if it were easier to work on these engines. With the right stuff, 300 HP with a naturally asperated engine should be obtainable. 250 HP should be very doable without compromising any streetability.
