Cylinder Head Service Kit for International Harvester 6-Cylinder Diesel Tractors

Description

When you start hearing that telltale valve clatter or notice your International’s not pulling like it used to, it’s time to get serious about your valve train. When you see coolant in the oil or white smoke billowing from the exhaust, you know it’s head gasket time—and putting it off only makes things worse. This comprehensive cylinder head service kit brings everything together in one box so you can tackle the top end of your 6-cylinder diesel without making multiple trips to town.

What You’re Getting

• Complete gasket set with head gasket, valve cover gaskets, and all sealing components that handle the extreme heat and pressure of diesel operation
• Fresh intake and exhaust valves that seal properly and won’t burn out after a few hundred hours
• Valve springs, guides, and keepers engineered to maintain proper valve timing and seating pressure
• All the small parts like valve stem seals and hardware that usually get overlooked but cause comebacks
• Quality components designed to work together as a complete system, not just random parts thrown in a box

Built for Real Farm Work

International Harvester’s 6-cylinder diesels are the backbone of serious farming operations—from the big row-crop tractors pulling 12-row planters to combines harvesting hundreds of acres a day. These 6-cylinder turbocharged and non-turbocharged diesel engines power through long days of heavy fieldwork, custom harvesting, and the kind of demanding applications where downtime costs real money.

Made to Last

The gasket materials are designed to handle the thermal cycling and high pressures of diesel operation without blowing out or losing compression. Fire rings around cylinder openings resist blow-out even if you’ve had some detonation issues. These aren’t cheap aftermarket parts—this kit uses quality materials that’ll stand up to the heat, pressure, and vibration of heavy farm equipment.

Good to Know

A successful head gasket job starts with proper diagnosis—make sure you’ve found why the original failed. Have the head checked for cracks and warpage at a machine shop, clean all surfaces meticulously, and follow the manual’s torque sequence precisely. This kit works on both turbo and non-turbo applications, but double-check your engine specs before starting the job.
