Don't know what hp those heads would add but if it is a daily driver,street only, I can't see where those heads would be needed with that cam.The heads would benefit top end performance but possibly hurt MPG and torque may drop at anything under 3500 rpm.But if you want more top end with that combo then the heads would be a plus.I would be interested in 0-60 difference between the two sets of heads,in a 327 with powerglide .If you got a lead foot like I do go with the 2.02 heads.
