Yes
All LS1's have 1.7 ratio Roller Rockers.
Roller fulcrum NOT roller tip.

Haven't heard of them being junk yet. According to LG they are very good rockers, at least coming from the factory. They are alot better than the rockers that come on LT1s. They aren't even rollers what so ever.

Yea, I was about to say I know my stock rockers were not roller by any means. The rockers are not all that bad stock as far as being strong but as was mentioned the bearings in some come out. My stockers were fine but finally went to shaft mounted rollers.

If you don't have a magnetic drain plug, you may not notice the rocker failure until they completely fail. The tiny bearings show up on the magnet.
