Looking for more HP from a 360

Yes, but which pistons? Flat top or dish? At zero deck or below? If below, how much? What I'm getting at is if this is a factory type rebuild with stock performance in mind then there is only so far it makes sense to go. It's going into a light car... I plan on a similar thing for my '65 but it will look like and run 273hp manifolding. But I'm starting with a flat top zero deck piston so the compression is a couple points better right off the bat.
