What's a good cam to hit low 12's

Ok, your at 12.8's already with good speed of 105 mph. You are already adding EQ heads, which will gain over stock heads. Then, your adding a stall converter (I hope it's a good one, they cost $$). Then your putting more cfm's on top. I think your at low 12's with just the heads and converter, IF you bought a good converter. The heads should put your speed up, and at 106-107 mph you should be lower 12's with a good converter. I don't think a cam swap is necessary
