What is the "tolerance" band on the resistors in question? Typically, carbon comps have a silver band for 10% or a gold band for 5%. At 5%, you could be + or - 11 Ohms on a 220 Ohm resistor.
The other question, of course, regards the resistors' intended use in the circuit. If they are being used as "grid-stoppers", there will be such an infinitesimally small amount of current going through, that it just won't matter much at all.
