Im trying to decide whether to keep with the old flat tappet cams or make the move to a roller. I dont need high lift at all around .590. So some pros and cons for each would be great. I have heard that rollers require more maintenance like valve springs changes more often and stuff like that but I dont know if thats because of the high lift that you can run with rollers? Another question I had was about cam additive for ZDDP whether you need it for rollers like you do for flat tappets and what kind do you guys use for your cams?

Thanks guys
