I am selling a SKI-DOO 503 F/C CYLINDER HEAD #420923590.

This part came off of a running machine, that we parted out. 

The 
SKI-DOO 503 F/C cylinder head #420923590
 was widely used on many Ski-Doo snowmobile models equipped with the Rotax 503 Fan Cooled (F/C) engine, primarily throughout the mid-1990s to early 2000s.
Compatible Models
This cylinder head is compatible with various Ski-Doo snowmobiles that utilize the 503 F/C engine, as documented by part suppliers and service manuals.
