Default LS6/LS2 heads

Looking at some 243 heads, how do you tell if they are LS6 heads or LS2 heads? Thanks!

I read somewhere that the non-Z06 valves have orange in the center of the new valve. To be sure, you need to weight them. I have been looking at the Z06 heads myself, and the cost is in the valves. If you buy them new, discounted the set is over $700 so if that is what you are looking for, be absolutely certain that is what you are getting.
