Head gasket SW4

WOpp · Feb 8, 2013

In am doing out of frame overhaul on my SW4. I am increasing the engine from 3.5 to 3 9/16 bore. I have been told there are two different head gaskets. one for each bore. How do I know my suppler got me the right one? Thanks

IH used the same head gasket as a C-169 or C175 engine on there 3-9/16 sleeve sets for C-164 engines. Used to be head gasket # 362746R2. Maybe R3 now.

Well, I'd expect the difference to be the holes for the cylinders. The standard head gasket will probably cover part of the open cylinders. The overbore head gasket won't.
