823 heads on L99
Happy New Year Guys!
I could not find a clear information and thus decided to put this question over here. My engine is L99 (2012 Camaro 2SS). I see my engine's heads have casting # 823. Q to L99 owners: do you have the same heads on your L99? Any difference from LS3 heads (I found that Ls3 has the same #): http://www.camaro5.com/forums/showth...ight=823+block Thank you camarads!

Most LS3s have 821s.

I haven't looked at mine. Might do it when I have some spare time. Is there any difference between them?

821 is LS3 with hollow intake valves.
823 is L99 with solid intake valves.
