LS2 uses first gen style heads with Cathedral shaped intake port, and 15 degree valve angle(same as on the C5 Z06 LS6 engine, but with cheaper valves) 2.00" I valve and 1.55" E valve

LS3 uses new style L92/L76 based heads with rectangle intake ports, larger valves(2.16" I valve, 1.61"(or 1.58")E valve, a shallower (same as LS7) 12 degree valve angle, and (in the Vette) a higher lifter cam(.550 vs .520)

I had asked this question earlier Bcannan
