I would build a zero deck stroker and use magnum heads.Make sure quench is set correctly with bowl porting and a gasket match and your looking at an easy 450 h.p on a very streetable motor (tons of torque and hi velocity heads) with built in detonation protection due to the quench.Strokers seem to "like" hi velocity heads which quickly fill the cylinders,as the increased stroke picks up piston speed. With the faster moving piston comes a need for speedy air fuel delivery,so I would also recommend a cam with fast ramps. Contact Hughs engines and have a look at thier cams.
