Is the "Ford Racing" flywheel SFI certified?
For that combination you'd want a lot of midrange, so I'd be looking at a Comp Cams high energy street roller profile. Their lobe 1476 has duration of 244@ .050", and .641" lift with the FE rocker ratio. Advertised duration is 288. I'd probably use that lobe on both intake and exhaust, with a 110 degree lobe separation, and degree the cam in so the intake centerline is at 105. This will give you about 8:1 DCR, which should be safe for pump gas with your iron heads and still make good power.

One thing I would be careful of is a guess on your static compression ratio. Get the data on that, don't just trust what your machinist says. Have the chambers cc'd so that you know their volume, and get the data on the pistons so you know how many ccs are in the eyebrows or dish. You need to be confident of your compression ratio if you are going to pick the right cam.
