Description

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.

PPE’s new ported Cast Iron Cylinder Head is the ultimate upgrade to your Duramax engine and eliminates any head gasket or cracking concerns. Cast from high-quality alloyed gray iron, the PPE Cylinder Head offers elevated fatigue strength, heat, and creep resistance, which prolongs the cylinder head’s lifespan significantly. PPE Cylinder Head also shares the same heat expansion rate as the stock cast-iron cylinder block - no more blown head gaskets.

Our CNC porting process improves airflow, enhancing power, fuel efficiency, and throttle response while reducing engine stress and turbo lag. By smoothing the ports and maintaining wall thickness, these heads provide increased horsepower and torque without sacrificing reliability. Tailored to each specific head, the CNC machining compensates for casting variations, ensuring consistent and optimized airflow dynamics. Whether you have a damaged aluminum cylinder head or a desire for better reliability and longevity on your Duramax engine, the PPE Cast Iron Cylinder Head is undoubtedly the best choice.

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 inch to +0.008 inch) oversized exhaust valve seats (Nominal size 34mm).

Requires the use of LBZ/LMM glow plugs on LLY engines

What a nice surprise
Color: Black, Color: Black
This purse totally surprised me. It is so nice. It feels rich, soft but structured. Looks way more expensive. I love it. Update. My only complaint after using is the magnet closure isn’t really strong so can open easily

Amazing bag
Color: Black
Omg this is seriously the cutest bag. I purchased the black so classy looking and I love that you can carry It 3 different way. It looks like an expensive bag. Can’t wait to use It at some weddings as a clutch and then a cross body or shoulder bag other days. . It has card slots in It which is so good when you don’t want to carry a wallet. I did put a small wallet my phone and lip gloss and keys and still have room.

Nice bag
Not a bad bag just not my favorite. Looks different once it came in the mail and the quality wasn’t as nice but still very spacious. It’s a nice daily bag but not what I had needed.
