Depends on whether your lifters are due for replacement (50k miles) because there is a short cut if using new lifters but owing the propensity for Evos to leak from the rocker base gasket (this is different from the cylinder base gasket) I would do the job long hand.
Rocker covers have to come off, rocker gear and rocker base come off, the pushrod tubes out, lifter blocks off, lifters removed and then cam cover (on some bikes this means removal of the front exhaust pipe).
Replacing the inner cam bearing is compulsory, using adjustable pushrods is not, so long as you are using a bolt-in cam.
If your bike has high miles (50k plus) it is a good ides to pull the heads, clean the valve stems, cut the seats and replace the valve stem oil seals or you may find an increase in oil consumption due to the build up of varnish on the valve stems tearing the seals due to the increased lift.
Ignore anybody that tells you to spend a heap of money on upgrades that they will never afford because it will run better just with the cam.

Thanks, that's all I needed to hear, I'll wait until I rebuild the motor in a year or two. Only has 40 K on it. I've done small block Chevy s but never a bike, when the money is put aside I will look forward to the winter project.

A good cam upgrade is really all you need and if you wait 2 years you will be kicking yourself in the *** for not doing it sooner. JMO

As far as what everyone else has said, it's true... cam is all you need for good street power. I will say skimming some off the heads may give you a little more excitement but for the average joe, cam is all you need.

No need to cut your pushrods... pull the rocker gear off, pull them out, and re-use them.
