Heads will help without a doubt for overall performance but may not be needed. You said your heads have been ported, and I have seen some E7's that flow ok with a port job. If you get some big heads low rpm power could get worse because of a larger runner and valve.
What gears do you have out back? Even a full race 306 that shifts at 8000rpm will be a dog off idle. You need gears to make up for the loss of low rpm power. Most cams will tell you this along with the proper stall speed if you have a auto.
