Yes they will drop right in with a valvejob of course,same size, lenth as ls1 valve, the main benefit is the lighter weight of the ls6 valves.Some have had breakage problems in extreme hp applications, seems the head comes apart from the stem.

The 02-04 LS6 valves are not the same length as the LS1 valves. They are slightly longer, but they shouldnt be a problem.
