M Cylinder Head

Gary Reif · Mar 11, 2010

Need some advice. I'm rebuilding an M cylinder head but not sure which valves I need. The head casting # is 6336-DC. Is this a distillate head or a kerosene head? When I dissassembled it it had kerosene intake valves and distillate exhaust valve in it. These are two different lengths. All the valve specs I have call for the valves to be the same length, these are not.
Thanks for any help anyone can give me.

Thats a early head and information is a little sketchy. Best information I come up with indicates the 6336DC head was used on both distillate and kerosene at the DC time. Later higher suffix ones DD,DE,DE,DF were mostly used for kerosene engines until some late suffix ones were used for distillate on some C264 engines. 6336DC original valves should be 48958D intake, 4859D or DA exhaust.
