Basically they are!
As stated above, different heads, cam intake but in my case, I have a 2002 (LS-6) motor and threw out the crappy heads/cam/intake that came with it. So what do I have, an LS-1 or an LS-6?
Better oil pump? IDK but assume it does about the same function and doesn't add any power...
keep the mechanic and buy him a beer

Perhaps you need to find a more knowledgeable mechanic.

ask the mechanic what he meant about the timing, other than that he sounds correct. Maybe you misunderstood the timing answer ... I think the oil porting was a little better on the 2002 - 2004 years.

Give the mechanic a chance, he may have been not really trying to go in depth on the subject. And quite frankly he may be really a great technician who knows his stuff and references the service manuals. Just because he doesn't quote the specs off the top of his head, doesn't mean he's not good.
