What cam to use in a 318

This will probably open up a can of worms as this subject has been well covered but I am interested in some recommendations that folks have actually built and ran. Here are the particulars. Care is a 73 Dart swinger 3.23 geared 25" tires factory high stall converter in 904 with a TF-2 shift kit. Engine is 73 318 .30 over, with 9.2 compression measured. Has piston upgrade and running magnum cylinder heads with Hughes springs. Intake is a Dual plane air gap type, 600 CFM carb. Running 360 manifolds for now into full length dual exhaust. I may run headers but as this is a weekend cruiser mostly I don't know if I want to mess with headers at this time. I know the magnum heads flow well and with a better exhaust I was thinking some kind of single pattern cam would be best but if I want to run manifolds and full exhaust I should have something with a little more exhaust duration. Heads have 1.6 rockers and I would like to stay below .500 lift to avoid guide to seal clearance issues. Not necessary looking for maximum horsepower like a magazine build but something that will take advantage of the engine upgrades for good usable power.
