im looking to upgrade cams. in doing that wuld i have to upgrade any other engine internals? and is it wirth spending tge money on it?

 

Need more info! What car do u drive? What is your power goal? Do u have access to e-85? Is money an issue? Etc...

 

You would certainly want upgraded valve springs and retainers as a minimum.....neutral balance shafts are a good idea depending what cams and rpm you want to rev to. Hp depends on which cams, supporting mods, tune, fuel choice etc. A set up with required parts at new prices would probably run around 1200ish plus install and a tune. If you are worried about money, i would look for other things to do
