Roller Lifters

Neighbor of mine wanted to know if stock LS1's had roller lifters. I do on mine, but it's not stock.
I'm not too sure.

I believe the fulcrum of a stock LS1 lifter has needle/roller bearings but the tip does not. If I am wrong I am sure someone will correct me. It is the tip roller that helps reduce valve guide wear, among other things.

I am confused on original post whether you truly mean lifter or rocker. All LS1's have roller lifters, however stock rockers are roller trunnion only.

In this statement above, he means "rocker arm", not lifter.
