I'd say go with the cam if you can, I'd probably also get a Standard Abrasives porting kit (about $40 from Jeg's/Summit) and port match/clean/polish the ports yourself. I just used my electric drill being I don't have a compressor at my house for my tools, the bits won't fit in a Dremel although you can use some of the dremel bits to get into small areas like around the valves. I'd maybe take off the heads while everythings apart and port match the intake runners and clean up/polish the exhaust ports. It may a little while and you'll have to buy gaskets/head bolts but it would definitely make a difference and help get hte most out of the cam/intake.
