Why Yella Terra Rockers?
Reduced valve guide and seat wear
The traditional metal tip on standard rockers literally drags across the valve tip as the rocker opens and closes causing high side loading on the valve. This inside force leads to irregular and rapid valve, valve guide and valve seat wear in many engines. The roller tip on Yella Terra roller rockers eliminates this side loading action, as a result engines rev quicker and freer with a crisper exhaust note and maintains peak efficiency longer.
Reduced friction
The use of needle roller bearings at the rocker fulcrum combined with a roller tip at the valve greatly reduces horsepower robbing friction in the valve train.
Component strength
Yella Terra aircraft quality extruded arms are the strongest made and are matched to massive ground trunions for superior durability to other brands. Oversize needle roller bearings are used for better load distribution. Yella Terra uses premium quality materials, carefully controlled heat treatment and precision grinding and finishes. This ensures reliability, minimum friction and long life.

how much lift is gained when going from stock 1.7ratio to 1.8?
would I need longer pushrods still, i have brand new 7.4 rods for my milled .010 243 heads, with 226/230 598/.608 EPS grind comp cam. also would 1.8 ratio cause me any PTV issue on my stock LS1 bottom end?
thanks,
Ryan
