I wouldn;t get to carried away on the cam, but something in the low 280 at .050 on the intake, and upper 280 to low 290 on the exhaust, with .775 intake lift, and .714-.720 on the ex. I personaly would run a 112 lobe sep. With the tighter lobe sep, it should equal the mid range tq of the old cam, but, it will make more hp up top.
Have you considered just re-working the heads you already have? You said they are un-ported correct? If thats the case, for A LOT less than new heads, you could pick up a bunch of power that way. A cam change, maybe an intake change, to a super Victor, or the smaller profiler, I wouldn;t use the big profiler for 7000rpm, but, a Super Victor, with some minor plenumn work, a port job, maybe bigger intake valves, and a cam, and you would go high 5's. And, the cool part, you could say, they are just some old 074 aluminumn heads, when your beating guys with Dart, Brodix, etc. You couldn;t imagine, how mad guys got, from my above example, with the 049 oval ports, how mad guys would get, when they got trailered by old junk truck heads, when they were running their cnc'd this or thats.
