hey guys, i just bought a vette partscar for the engine. its got 35k on it. im in the process of ordering parts for it such as an opti and water pump. im also going to be putting in a cc503 cam, im confused as to which rockers i should go with. ive heard some people say 1.6 rr are amazing but i have also read that you dont need roller rockers, that the stamped steel ones work fine as well. any input would be great. yes i am also changing the timing chain to a double and im getting new springs
