Did GM update LS1 rockers?

I had heard GM at redesigned the rocker arms after a certain year. I have a 99 LS1 and have been given a set of 2004 rockers and was wondering if I should swap them out.

I hant heard anything about this. The only revision on stock rockers that I know of is the harland sharpe rebuilt trunions which keep the needle bearings from spilling out, which the stockers are occasionally known to do.

Negative...I had a little incident with mine (my fault) that required me to replace one of the rocker arms. I ordered a brand new one, and they were identical to what came off of my '02.
