Help with cam selection

On the suggestion of speaking to Dwayne at porters I will probably go to a solid flat tappet cam instead of a roller cam. Still need to decide on grind but will have the shaft nitrited for strength. What grinds and lifts are others using to reach the mid 11's and still be streetable. He had no concerns with the 2x4 setup or gearing and thought 11's wouuld be very reachable with everything else I was planning on using.
