Deciding on replacement intake (318, details in post)

Why does it seem like everyone what's to put 360 heads on their 318's? I asked these because they drop the compression off unless you have them milled like 0.070" and that has to cause port alignment issues also wouldn't that affect the push rod length? Just asking as I don't know these things as a fact or from personal experience.
I've put 360 heads on 318's more than once, and I've always gained performance. Flow over compression. I always cut them about .040
