Neal, think about the question you ask. Your a bright individual. If what you were asking was true, where would the other exhaust gases be going????? Even if everyone of your exhaust valves where burnt, whatever is being burnt has to go somewhere, out the exhaust pipe. No chance of one burnt valve will be able to suck enough back though the length of the exhaust pipe to over come the other exhaust pulses. Sounds like an Urban Legend to me.
