Was the same engine miss there before heads r&r? Has fuel injectors been checked on those cylinders? Is miss at idle and under acceleration? Have vaccum leaks been checked?

The cylindes that are effected indicate an intake leak. Check injector connections if good. Consider pulling top intake and give close look at gasket seal.
