In general increasing the LSA will decrease overlap and overlap is the "chop" producer.........so the 112 will be choppier than the 114. That being said TSP has in the past has had some advance ground into their cams too.

112 is the tightest with out PTV issues and I would call them to make sure they can't talk you into a Ms4... LOL I love my MS4,

Fill in me on the slight differences between the MS3 and MS4....my main goal is to NOT have to do anything with the stock ls6 heads on a 01 z06. I will be going with TSP's package with the hardened rods, springs ect. So will the ms4 be good with the stock heads on the z06? I think ill go with 113lsa only because i want a good chop but i will use the car for some daily driven. So i dont want it to obnoxious

Yes the ms4 will fit as long as you keep the stock valve size in the heads. If you get larger valves you will definately have to flycut in order to get the MS4 to fit.

i don't believe that a MS3 would fit on bigger valves either.

it seems to me that even if the MS3 (or 4) were on a 114 or 115 it would still have a pretty choppy idle... the MS cams have a bunch of overlap.
