Here is some good reading for you and your friend.

The only misprint I saw in there was that it says all 6.0 had flat top pistons. This is not true, the LQ4 have a slight dish to them while the LQ9 are completly flat. I have seen this with my own eyes.

LQ9 have beefier rods and flat top pistons with moly coating on the skirts and thermal barrier on the top.

Everything thing else is the same.
