I should have been more specific but these are my basic parameters:

1. Aluminum

2. Must be capable of flowing enough cfm to support 422 ci (idealy more than 270 cfm after porting)and accomodate a 2.100" Int. valve w/o shrouding.

3. Reliance on stock-style valve-train design.

*** I've ruled out W2's because the engine will be used in either a truck or a van (W2 headers are not designed for use in a VAN/TRUCK. All other Mopar W-Series heads are not considered for similar reasons as stated above. I realize that with the right machining, anything is possible; only, the basic head must provide the foundation to perform the required work to reach these goals.***

{BTW, the 2.100" Intake valve is a recommendation for engines larger than 420 ci and is also supported by the Reher Morrison belief that (52%)(Bore)= Minimum Intake Valve Size. In this case the minimum Intake valve size is 2.132"}.

At this point,cost is second in priority to performance.
