engine math! milling heads + intake

so basically what you're saying is that instead of these 360 heads, i should run 302s with 360-size intake valves? what if i kept the 360 heads but didn't modify the intakes, kept them at 1.88, but milled them like they did in the mag? i know the runners are large, but i mean, i already have these heads, and they got good power with them in the magazine. everything i have heard about the factory 318 heads (early ones, like mine) is that they have too small of valves, despite their smaller chambers, and they just didn't flow well.
