Curious, difference between 2002 LS1 & LS6?

I know that there are at least a few parts shared between a 2002 LS1 and a LS6, the intake manifold, and the block are at two that I can think of.

I believe the LS6 has different heads, and I'd guess a different cam, anything else?

Starting mid model year 2001, the C5 LS1 also got the larger MAF/throttle body. Only difference is the LS6 MAF has it's screen removed

I think this thread needs a summary:

difference betyween 2002 Z06 and 2002 C5 LSI powertrain are:

* heads
* cam
* lighter pushrods
* descreened MAF
* different PCM tune
* ZO6 has M-12 tranny
* Z06 has hardened carrier case
* air box lid

exhaust difference:
*pup-catless H pipe
*titanium mufflers

starting in 2002, I do believe this is a complete list... ???
