360 Magnum Build

Contemplating doing a 360 Magnum build, Horsepower goal somewhere around 350-450 at crank

The last time I did a 360 magnum we just stuffed a custom lunati cam in it and ran everything else stock with dougs long tube headers. Wanna get a little bit more into it this time.

What heads do y'all recommend? I don't want to use the stock ones this time around.
