Part of the thrill of a nasty cam was the mechanical tingle induced downstream in the tubular headers and (less so) chambered mufflers. Cutouts will sound like crap (by modern standards, especially), and will not produce the Killer effect you are after.
It's a shame many weren't around for the sensual experience of a corked up big-cam small block. It actually was what you want !
