Roller Rockers - 95 SSei
Okay.. so according to Pat, the 95 SSEi has 1:6 ratio roller rockers.
Assuming that I had the supporting exhaust modifications completed, would 1:72 roller rockers be a good upgrade? What would higher ratio rockers do for performance?

also....
Stock rockers have a metal tip that drags across the valve tip. This creates high side loading on the valve and increased power loss due to friction.
Roller rockers have a needle roller bearing on the tip that effectively eliminates these problems. Reduced friction means less parasitic loss and less heat.
Kit comes complete with everything needed to install including all retainers and valve cover spacers.

Stock Intake Cam Lift .250 Lift at valve with a 1.6 Rocker .400 1.72 rocker .430 lift
Stock Exahust Cam lift .255 Lift at valve with a 1.6 rocker .408 1.72 Rocker .439 lift
If we looked at the series II rockers, the 1.9 would be .475 intake and .485 exahust
