Mopar Performance aluminum Commando head

Chris;

The big port Comando head need work OOTB, but once you deshroud the valve from behind the chamber wall, the'll flow well. However, while your there, bowl blens/pocket port the head. These heads can be ported preety well and flow over 300 cfm.
The do use off set rockers, so the stamped steel rockers are out.
The direct bolt on aluminum heads would be quicker and easier to do with less potential than the big port units. This is due to the port layout. They should still perform well.
The cc for the big port head is OOTB @ 55 or 53. I forget. But it needs to be opened up (For more cc's) before the heads shines.
How well any cam performs in a car is more than just head flow or material being use.
