Description

50 States Emissions Legal (E.O. D-701-PENDING)

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 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.

Each head comes complete with upgraded valve train components. All valves are made of superior materials and fully nitridated. The tapered valve springs' higher spring rate and lighter retainers/locators enable faster response during higher RPMs and eliminate valve float.

Powder metal valve seats provide superior wear and heat resistance. The denser and stiffer material properties from the cast-iron construction also significantly reduce engine clatter.

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).

Shipped well
Fit Type: Relaxed,Classic, Color: Black, Size: 40W x 38L
As a tall person, things are normally difficult to find. This seller did well on the packaging and shipping, so I wanted to support them in order to still have a vendor that sells my sizes. These jeans in particular did fit me nicely.

The Wrangler Jeans sized 62x28 were incorrectly tagged for size.
Fit Type: Relaxed,Classic, Color: Antique Indigo, Size: 64W x 30L
The exterior size tags a adhesive strip on the leg were marked were marked 62X28. these tags were the INCORRECT . the jeans have a white cloth tag sewn inside the garment on the left front pocket that clearly indicated these jeans are size 60X32.. It's a case an of improperly marked pair of jeans. looking at them on a display shelf one would have to believe this pair of jeans were size 62X28. i do not old the shipping department at blame. I need to exchange them for the proper size.
