Big Cam choice

Big Cam choice
I need help choosing a Cam for my Automatic 98 TA.
I have a full set of bolt on's and just ordered a set of Absolute Speed stage 2.5 5.3 Liter heads (not milled)
I am looking for high 10's.
I have a 4200 Yank converter on the way, and a stage 4 FLP tranny sitting here. Car is full weight. I have ran 10.7 before with a very small cam and a set of unmilled 5.7 stage 1 heads. With a 150 shot. I decited to go NA and get rid of the juice and have ordered everything to help me stay in the 10's except the cam. I also have a 90mm TB and Intake coming.
I drive the car around every now and then. No rain days, and not very often when there is a lot of traffic.
The bottom end is stock. Here are a few ideas I see
234/238 duration, .598"/.605", 112/114lsa
238/242 duration, .605"/.610", 112/114lsa
232/236 duration, .595"/.602", 112/114lsa
232/238 duration, .595"/.605", 112/114lsa
234/238 duration, .598"/.605", 112/114lsa
236/240 duration, .595"/.609", 112/114lsa
236/242 duration, .595"/.610", 112/114lsa
I do not want to fly cut the pistons. So if any of these cam are to big without flycuting then let me know and I can rule them out. (I am guessing the last 2 will be too big)
Also would it be a bigger advantage to go 112, 114 or a different LSA. I spoke with a cam guy earlier and he suggested a 111LSA, just dont know how the driveability would be.
Also I would like to shift between 6500-6700 RPM's. Any advice/suggestions would be great.
Thanks

I think any of those cams will get you were you want to be with a good tune of course. My car had some problems when i ran what i did in my sig and that was on some shitty et streets and a tight 3600 stall for the bottle. In full trim to. Put a g5x2 in it and some slicks and with your convertor you should be tens all day. If your pistons were fly cut i would go a little bigger but is it worth fly cutting pistons in the car or having p/v problems. I don't think it is worth the little extra you will get out of it.

Thanks for the reply's so far.
I dont think there will be a huge difference between the cams, and want to have a somewhat streetable car. I take it to local car shows and cruise the beach, so the car is driven, just not very often.
The G5X2, does this cam require flycuting the pistons?
If not it might be a idea.
The heads I have make great mid power, and was really looking for a cam with fast ramp rates, but not huge lift numbers. I heard that Cmotorsports might be coming out with some new cams very soon.
