I worked for many years in the 60's for an engine rebuilder in
Ecuador, burnt valves also have to do with a TO LEAN fuel mixture, as this also
tends to increase heat in the cylinders. In case of worn valve stems
and/or guides in most cases our workshop would ream out the guide and fit
valves with oversize stems when available. Sealed Power used to supply quiet a
variety of valves with oversize stems, in most Chrysler applications they would
be 0.005 - 0.010 and 0.015 oversize.
