Default 2000 Mustang GT heads with cams?

ok so i have a relatively stock mustang gt and would love to add some cams. what i was wondering is what does pi mean on the heads. does that mean that they will work with a new set of cams with new springs? any help?

Look at HiTech stage II cams, no need to swap out springs, unless your engine has some miles on her or since your already there.

You already have PI heads and cams. Cams will be good for some power, how much depends what specs you go with. As far as valve springs, see what the manufacturer says, but most aftermarket cams will raise your redline up a bit and you will need the right springs to make the most of them, the stock ones will float too soon, or worse, may break. As far as I'm concerned, when you switch cams, you go with the recommended spring at the same time. Do it right or don't bother.

As long as you get moderate cams, like the hitechs mentioned, there's no modifications needed to the heads. Just make sure whoever installs them degrees them in, as the factory cam sprockets can be up to 7 degrees off.

search youtube for hitech stage 2, and you'll see. Any larger than that requires valvesprings, and then you have to check piston to valve clearance.
