Has anyone tried the Odessa Cylinder Heads for 5.2/5.9 Magnum ?

Stoplight to stoplight car, with an attitude, was hoping for some heads @250 CFM @ .550 lift, hopefully around 450 hp , then add a 150 shot of N2O.
I'd love a set of Trick Flows but not willing to spend that much $
So build a 408 stroker with the RIGHT cam and intake with these heads and you will be an easy 400+ HP. But you will also be 450+ lb/ ft of torque. Torque, my friend, is what wins stoplight to stoplight if you can hook it up and produces the most SPG: Smiles per Gallon.
