Valve relief orientation

I’m assembling the 496 and see no indication as to which way the pistons go and which ones belong in which bank. I also can’t put the rods on until I know which piston goes where bc of the chamfer/flat side and that orientation. So my question is which valve relief faces the front of the block? The larger or smaller one? I thinks that’s oughtta solve the whole equation.
