It all depends what street friendly means to you. I had a 246/246 hyd roller in the 512 inch stroker in my Coronet and I decided it was a little too big for the type of driving that I was doing. It worked great on the freeway but was just a little too rumpy around town. My new engine has a 239/245 hyd roller in it and it seems to be a better fit. Either of the cams you posted should work okay for what you're describing. They are fairly small and will kill off a bunch of power up top, but they should give you a fairly smooth idle and plenty of torque down low. Your headers are too big for what you are doing but you might not be able to change them at this point. For bottom end torque you probably don't need anything larger than 1 3/4 inch header.
