Looking to cam up

I have a Voodoo 256/262 cam in my 360 that I swapped over from my old 318 but I think my engine could really use a bigger cam. It's .060"-over, KB flat tops (10.4:1 comp), untouched Magnum heads, Air-Gap intake, Hedman shorty headers 1 5/8" and 750 Mighty Demon (when I'm racing, 625 cfm AFB for the street). 904 trans with mild shift kit and stock converter; I have an 8 3/4" rear and plan on swapping between 4.10 gears for the strip and 3.23 gears for the street so it needs to have decent low-end.

The main issue I'm running into is max lift at the valves, the heads are stock Magnums with the Hughes retainers and 'straight' springs #1110, I believe this is good up to .525" lift (am I right??) which is very easy to go over with the factory 1.6:1 rockers. One I'm liking so far is the Bracket Master 292 .480" but people have mentioned it's pretty old-school. I would go with the 268/276 Voodoo in a heartbeat but I'm afraid the exhaust lift will be too much. I'm open to other brands too but they seem to share pretty similar grinds when it comes to the conventional slower-ramped profiles.
