which varient of 6.0 head??
I believe most or some LS2 engines 6.0 ones have 243 castings, IE LS6 heads so will work, some aftermarket or maybe another casting of 6.0 heads have bigger valves etc that will NOT fit the 5.7 bore.
my pal has a set of 243 LS2/LS6 heads from a LS2 engine, valve are just not the sodium filled ones

yeah they are the LS2 243 heads:
The LS2 was introduced as the Corvette's new base engine for the 2005 model year. It also appeared as the standard powerplant for the 2005-2006 GTO. It produces 400 bhp (300 kW)@6000rpm and 400 lb·ft (542 N·m)@4400rpm from a slightly larger displacement of 5,967 cc (5.967 L; 364.1 cu in). It is similar to the high-performance LS6, but with improved torque throughout the rpm range. The LS2 uses the "243" casting heads used on the LS6 (although without the sodium filled valves), a smaller camshaft, and an additional 18 cubic inches. The compression of the LS2 was also raised to 10.9:1 compared to the LS1s 10.25:1 and the LS6s 10.5:1. The LS2s in the E-series HSVs are modified in Australia to produce 412 bhp (307 kW) and 412 lb·ft (559 N·m). The LS2s in the Chevrolet Trailblazer SS and the Saab 9-7X Aero are rated at 395 bhp (295 kW) (2006-2007) or 390 bhp (290 kW) (2008-2009) and 400 lb·ft (542 N·m) of torque due to a different (sometimes referred to as a "truck") intake manifold that produces more torque at lower RPMs.
from wiki!
thats the ones my pal has from a LS2 GTO, get then if they are 243 castings, bout 20+ hp over stock on stock cam etc
