Then you probably dont wanna go after a cam if you're noobish.

For the VS cam, you can run it on a stock motor. Some people run 90# springs with them though. It'd also be a good idea to replace the timing chain and damper if doing a cam.

But besides that, You'll need 2 coolant elbows to do the LIM gasket. They almost always break when removing the alt bracket...

You should also get new valve cover gaskets, since you're there...and the rear one is a PITA to replace by its self.

IF you cam, look at $325 for the cam, and about $125 for springs, timing chain, and damper. Plus a few bucks for a front cover gasket, and you'd need to tune the computer..which prices vary..
