you can't have a head "bored out", it's a flat surface with a hollow dome where the valves and combustion chamber are. If you mean having the head milled, then no you do not have to have the cylinder head milled when you have the cylinders bored out. However, it's always a good idea to have the cylinder head surfaced and cleaned, and possibly have the valve seats ground while the head is off.

You can have the head deshrouded to match the cylinder bore, but it's not absoluetly necessary. Most people leave their heads alone when they run an 84mm bore, but you should always check your clearances to see if they're still in spec with the 84mm pistons.

I know my asshole from my cock 
I was talking about the "Bowls" in the head, I was just curriouse if most people left it alone or if they had a bit shaved off the edge of the "Bowl" to make the combustion chamber match the cylinder walls... Thanks
