The aluminum V10 cylinder head has had lots of porting experimentation by shops,
but the iron V10 head ports are supposedly very different,
smaller in order to get peak momentum airflow rates at lower rpm for bottom end torque.
The official Chrysler press release claims the iron V10 makes 90% of peak torque at only 1200 rpm.

Iron V10 heads have individual exhaust ports on each cylinder
unlike small block 5.2/5.9 cyl heads,
but i wonder if one of the two different official Mopar Performance sold
Magnum 5.2/5.9 plastic intake templates
might be a good guide for intake side porting?
The shapes of the V8 and V10 combustion chambers are very similar.
