I have a very loud ticking that a shop told me was coming from the valvetrain. I want to fix this but need some help, I am going to look into getting new springs lifters and pushrods, for now and maybe later a new cam. I would like to know what you guys would recommend, and list individual prices for me if you know them, or ball park figures. ALso if I plan on eventually getting a cam, what sert up should I get for all this
