Disassembling a top end is kind of involved. It's a little more than bolting it up and going. Even with a kit, you will need some extras. I went with the TFS top end kit, and sub-ed out the cam for one from AFM. Added to that, I went with a bigger fuel pump, bigger injectors, MAF to match . . . oh hell, just read my sig. Everything but the suspension and gears I did to support the HCI, and make sure I was taking full advantage. The thing about the intake spacer, valve cover oil cap and elbow adaptor are right too (not expensive, but you will need them).
Also, dont forget that to pull the cam you need to remove every accessory. You need to drain the radiator and block of coolant. You will be breaking every factory seal on the top of the motor (hence leaks). Depending on other supporting mods you may elect to do, you may end up with further complications.
There's all that, and you should plan on getting a dyno tune.
Not to rain on your parade. I love my car. It just took a lot of work to get er done.
Or if you really want a bolt up solution, go Kenne Belle!!!

You'll have practically the same performance results, plus tons of low end.
