Choosing the right stroke for a 340

Thanks so my set up is a 1970 Sport Satellite 904 auto with 3:55 rear end. Heads tbd but want to go with aluminum like eddy or trickf. Mostly local driving no strip racing. Want it reliable but would like that flat torque curve a stroked engine provides. Have a high rise square mopar intake with a 4150 650 Holley. Would like to do a roller hydraulic cam.
Stroke it, small street solid roller cam, trickflow heads/intake, tti step headers.

Itll be all you want and then some without being radical sounding...maybe a little..
