Single or Dual Pattern Cam

I've been reading what I can find on torque cams. What I can't understand is if a wide lsa is not good for torque than why does the cam manufacturers list their torque cams with a 110*-112* lsa?. If I run speedmaster cylinder heads with 170cc intake runner's and 2.02"intake/1.600" valve's with a comp valve job and back cut the valve's and have the bowl area cleaned up, would those cylinder heads hurt midrange torque and power? Also would a single pattern cam be a good idea? Or would 5.2 magnum heads be a better choice, that is if I can find them for a la intake manifold bolt pattern? Somebody recommended a Howard's cam that has 255* / 261*, 208* / 214*@ 0.050" and it has a lsa of 110* would this cam work with a 9.40:1 cr without having to back off the timing? I'm trying to do as much research as I can but there's a lot on cams that I don't know about, thanks for your help and patience.
