Jeff,
Stuffing means that the floor of the intake and exhaust ports is raised by putting a piece of metal of the appropriate thickness in the bottom of the ports. Also available are sheetmetal tongues ( they look like a gasket with a tongue sticking out) that do approximately the same thing but not as well, according to some.

Because of the size of the ports the gases flowing through go at a slower speed than in a smaller port. See my posting iron vs aluminum heads.
