I am going to install these cams myself so I am trying to do a lot of reading and thinking and planning about what I am going to do to install them. I cannot find a write up anywhere on how to install them. I know they are NSR so could I just use the frpp hot rod cam Ford instructions to install these? Any help will be greatly appreciated thanks! Also why do I need new cam phaser bolts if I do not even remove the old ones during installation? Or do you and I just overlooked it? Another question I have is do I need to get 3.73 gears or 4.10's with these cams? I currently have the stock 3.55 gears.
