Just bought those cams. the third cam down. Split duration built for "turbos" one. The vendor is pushing me to get valve springs with them? i know eventually i want them and it is a good precaution to buy them. My question to you guyz is it absolutely neccesary for me to Instal the springs with the cams? or can i just install cams with stock springs and not have to worry???
