cam for my 410?

I have a 410 stroker kit for my 360, cast crank, h beams, forged pistons. I want a streetable motor with around 400 horse, but am getting mixed reviews on what cam to use, I have gathered that I will use a hydraulic flat tappet for reliability, but im not sure what lift/duration. any advice?

69 dart, manual trans, 3.55 gears

What heads?
