LS6 has better valves. But yeah, other than that they are the same.

Take a look at the GM Performance parts catalog. It will give you the info. Also if you are considering them make sure you don't pay too much. A new set is $640 from Scoggins.

Yeah, or for an additional cost add their dual valve springs.

I have a set of these, they were measured to have a chamber size of 61cc. the 799s were supposed to be used on LS2 motors and the later 5.3l truck engines (or so has been posted on this forum)
