Default 6.0 LQ4 and LQ9 differences....engine is apart, how to tell?

I am thinkin about buying a motor off a guy at a machine shop. Its a 6.0. Block casting is 12551364, and heads are 317.

Its all apart right now, is there any numbers off any of the parts that will specific distinguish if its an lq4 or lq9?

I apologize if this is the wrong forum, I tried searching but cant get it to work...
