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).

An average table support.
These table legs are made of "jointed", threaded, 3/4inch steel pipes and it is imperative that they are assembled correctly and evenly; if not, the table will be wobbly and unstable. Need to ensure that the joints are fully tight. The assembly instructions are vague, so you may face some frustration during assembly if you're not too mechanically inclined. It is possible to modify the design of the legs to meet your specific needs, but you may need to purchase additional 3/4 inch piping and couplings at your local plumbing store. Good luck!

A good idea that didn't work out
The pieces are not labeled at all, the paint on the threads makes it difficult to get a good tight fit between the pieces, and the way the pipes are screwed together there are two opposing corners that always bow in an make it look like it's going to fall in. It's also really difficult to make level. I really wanted to like this because it fit EXACTLY what I wanted to use it for, but I just can't trust it long term which is why I'm giving it 2 stars.
