360 LA or 360 Magnum Whats the difference?

I seem to recall that parts listings went from 67 to like 86 or something. also does the LA intake bolt up to magnum heads etc? In short I think the magnum was how they converted the old LA to Fuel injection just like Ford 5.0 etc. roller valvetrain Fuel injection make power more efficiently until they came up with the next gen engines.
