No problem doing all this with the head on.
Lube the new cam up well with special cam lube, or some hypoid gear oil.
Don't turn the crank over with the cambelt off of course, and make sure the new cam is bolted down turned to the same position as the old one.
You need a method of tensioning the cambelt properly.
Haynes manual has a method of doing this, using a spring balance.
