6.0 Liter cylinder heads

So who can tell me the difference in all 6 of the 6.0 liter GM engines? I am looking for some cylinder head descriptions. Like cc volume and flow data.

I haven't a clue what the differences are, but if you go into the LS2 section, you should see a sticky that'll say the differences.

The 01 and later LQ4 and LQ9 6.0s share idential heads, casting numbers 317 or 035. They have 72cc chambers, 2.00 intake and 1.55 exhaust valves. 99-00 LQ4s had iron heads with the same specs as the aluminum 317 heads. LS2 6.0s share heads with the LS6, casting number 243. They have 65cc chambers, 2.00 intake and 1.55 exhaust valves but differ from LS6 valves in the fact that they are not sodium filled. Flow data can be found on www.smokemup.com
