I would use a quality brand name head gasket rather than a cheapy one. Do a search about retorquing head gasket after a given number of miles. You already have Europe's 9.25 to 1 pistons. If everythings in good nick that's about it unless you want to go to trouble and expense of balance and blue print route. A hotter cam will raise HP to a higher RPM if that's your driving style. But with any engine mod without doing a total package you're only going to get a fraction of a benefit of a piece meal approach.
If you skim the head make sure it's minimal (10 thou or less) or you run into slanted stud to hole issues.
