There's a roller wheel at the tip, and there are roller bearings in the fulcrum as well. Stock stuff, no rollers anywhere.

Yes I know about the stock ones, I have the factory upgrade kit with the 1.7 ratio, new springs and guide plates. Hoping they would allow more hp. Ported the stock heads, back cut the valves. M1 intake racing Q-Jet. I'll see this spring.
