The XPZ is a great cam, you don't need any kind of machine work for the install. Stock pushrods and lifters are fine, don't use OE-Rs. 130# springs will be fine as well.

For the double roller make sure that you get a machined oil pump cover.

With intercooling pretty much just get the biggest FMHE that you can, looks like wbodystore covers the basics for an IC install.

For tuning you might want to start out with something like a 3.4" pulley to get a baseline tune. The 3.2" is good for what you're wanting to go for.
