Tq is king on a heavy car. Hp wins races in light race cars. So you basically need both. I wouldn't go extreme that kills the tq under the curve.
How much street driving are you still going to do? The bigger the cam, the worse that gets.
TSP, Brian Tooley, Cam Motion, JRE, GPI, Katech ... they know their stuff with LS and 5th gen cams. Tell one of them exactly what you want the car to act like and go with a complete package approach all from the same shop that has dyno'd/spintron tested that combo. Valve train stability is the key to survival. It's a packaged approach that works. Katech has done a lot of spintron testing and has their cam profiles that they know are bulletproof.
Biggest most common mistake in modding a heavy street car is too big a cam.
My vote would be shave the heads while CNCing for 11.25ish compression. Then something like a Cam Motion Titan III. It'll still drive decent on the street, and be a tq monster that revs out nice. Lift is not too crazy so all it needs in the rockers is a bronze bushing trunion kit.
LSA wise. in general a 113+4 will still be nice and streetable with a nice lope. 110 is choppy as hell. Great for a race car or if your 16-18 yrs old on the street. But that extreme choppiness gets old fast trying to drive slow around a city. I know someone that put an ASA cam in a LS3 crate motor for a restomod. Hated it. Finally stuck a Cam Motion titan II in it...awesome car now very driveable and fun. I tried to tell him...the ASA cam was a race cam... in light race cars...
