Don't shave the head. Advancing the cam will cause the intake to close sooner and increase dynamic compression. Increasing compression also creates more heat, so if it's a concern don't make it any worse than needed. Also shaving the head will bring the cam closer to the crank, retarding the cam timing - not what you want.

How about shaving the head and advancing the cam to restore initial timing ?
Wouldn't it be better overall (high rpm included) ?

That's a good one, thanks !
Step one, tune carb and step two work on plug gap, right ?
