cb650 cam chain with new gaskets?

aiight, so i'm tired of the 650 marking its teritorry on the bottom of my pant legs so i ordered a gasket kit. not very familiar with bike motors, i'm an air coole vw guy (although i fucking hate that "scene" i still like the cars, but then again, i don't like any other fucker's car but mine.. ah, frustration) and besides the fact that it's air cooled, well, i'd be more comfortable taking the thing appart and changing the gaskets if the pistons were doing each other sideways instead of standing up.

anyway, how do y'all feel about changing the cam chain while i'm at it. i ask cause, well, i know it's supposed to be semi normal to hear the engine click but maybe it's too much.. i'm not sure, i don't know, that's why i'm asking.
