P1 Mfg K084-H01S. Fits Kubota V2203 & V2403 4cyl Diesels and possibly more.
Includes 18 studs/washers/nuts, 1 pack of lube, and 1 brush. Fasteners are made in the USA!
 
This head stud kit was specially designed through a collaboration between me and P1 Mfg.
I wanted a head stud kit to help hold the engine together once I started applying boost, even if only a little bit. The V2203 uses a whopping 18 head bolts!  By upgrading to this head stud kit, you can live with the peace of mind that your head gasket should live a long, healthy life.
