So im trying to figure out if i should upgrade the springs when i do my rocker install on my 2002 Gtp. Right now i have a set of 1.8 yella terra rockers waiting to go in, and currently would like to stay where im shifting which is about 6200 Rpm. My main concern is wearing out the timing chain dampener since its my daily driver right now. Has about 130K on it. What would you guys recommend i do?
