I want to do a cam swap. And I want to learn as much as possible before I hit the buy it now button. If I do cam and springs and not rocker arms do I have to change pushrods. My second question is at what amount of lift on the cam do I need to change push rod length. Thanks guys.

It's not that simple. Your best bet is to go get yourself a Comp Cams adjustable pushrod measuring tool. If you learn how to use it it will tell you exactly what your looking to find out here. Also make sure you match the springs to the cam your buying.
Good luck!!
