The factory 360 magnum cam (at least in the 94-95 models were right around 410 lift, the dur. is horrible even at 50*, i had mine re-ground through bullet cams, Tim was limited to what could be done because of its "lack' of any real lobe, We settled on this useing factory rockers (.477-.477, .218-.218 @50, went from a 114 too a 112), this cam even though it has "great" torque lacks in anything above 5200, its about finished, but it runs very very well.

I'm running a stock 904 with a RMVB & an 11" 2800 PTC.

I know you said the headers are not an option right now, put them on your list soon, i'm running the cheapo summit 105.95 headers, i will say thay are NOT cheap by any means, the construction is very good along with the fitment, much better then some headman/hookers i've had.
