The Ford Motorcraft KC3Z-6079-CA (EVG-1) 18mm Head Gasket & Upper Seal Kit comes with everything needed to reassemble the top end of your 2003-2006 Ford 6.0L Powerstroke engine. The head bolts on the 6.0L engine are known to stretch and it can blow out the head gaskets. A blown head gasket causes the coolant and motor oil to mix, requiring the gaskets to be replaced. The entire top end of the motor must come apart to replace the gaskets, and many shops remove the cab from the frame to make getting the rear head bolts easier. 

This kit is assembled with genuine Ford components and is the same high-quality parts your truck was assembled with. This reseal kit includes the gaskets, O-rings, and dowels required to install the heads, valve covers, intake, and exhaust manifolds onto the short block.
