With the bigger cams you don't need head work, they need the pistons machining. You also lose the camshaft trigger for the cam position sensor which might throw up a fault code on a standard ECU. But that doesn't matter anyway because you'll need throttle bodies and another ECU anything with other cams.

whether you will need to machine the piston is depends on the lifting of the cam.
you might need stiffer valve spring as well in some case.
but how about the lifters then? as i see most hardcore cam require to use solid lifters, why was that?

It's the duration that dictates the need to machine pockets into the pistons. The duration tells you how soon the valve opens and how long it stays open. The sooner it opens the closer it gets to the piston - initially the valve moves downwards faster than the piston moves down the bore meaning extra clearance is needed.
Again the longer duration means the opening ramp of the cam opens the valve quicker (in order to reach full lift) meaning a stiffer spring is needed to keep the follower in contact with the cam lobe.
