it's pretty expensive, I doubt if the blocks are made that same way.  That being said, I know as much about HD's as I do 14th century poetry.

Then we can stop every gas fill up like the F1 cars and change the air charge tank for the pneumatic valves :)

wasn't BMW playing around with such in the 7 series a couple of years ago?

the advantage of a cam in block motor physical size and weight, due to simplicity.  obviously overhead cam provides much more airflow potential (torque per cube, basically VE) and higher rpm capabiliy due to direct acting geometry, but at the expense of more weight (larger heads) and 3 more cams (in the case of a "V" DOHC)

pick you flavor, nothing wrong with either if done right :)

you could have the best of both worlds with an electromagnetic or pneumatic valve system, shrink the heads and dump the bump sticks.
