DURAMAX HEAD GASKET SOLUTION KIT 04.5-10 LLY,LBZ,LMM

This kit will provide you with 2 new cast iron PPE Cylinder Heads, PPE Head studs and Grade C head gaskets. We have combined this package to simplify the ordering process of these major components. Please allow 1-2 weeks for processing and shipping.

Cylinder Heads The OEM Duramax cast-aluminum cylinder heads fall short over time - the different heat expansion rates between cast-iron engine block and cast-aluminum cylinder head cause head gasket scrubbing, and eventually blown head gaskets. The aluminum cylinder heads are also prone to warping, melting, and/or cracking in high-performance applications where excessive heat is introduced.*Important Note: The valve seats of the PPE Heavy Cast Iron Cylinder Heads are installed with an interference that maximizes the durability and lifespan of the cylinder heads. Such interference might not be optimal for extreme-performance applications where a significant amount of heat is created. For those applications, PPE suggests that the exhaust valve seats be replaced with higher interference (+0.006'' to +0.008'') oversized exhaust valve seats (Nominal size 34mm).
Requires the use of LBZ/LMM glow plugs on LLY engines
