Over time, the OEM Duramax cast-aluminum cylinder heads exhibit shortcomings. Due to the disparate heat expansion rates between the cast-iron engine block and the cast-aluminum cylinder head, issues such as head gasket scrubbing and eventual blown head gaskets arise. Additionally, the aluminum cylinder heads are susceptible to warping, melting, or cracking, particularly in high-performance scenarios where elevated heat levels are 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.

I ordered this item 1/12/25, received 1/14/25. It was too slow and definitely wasn’t a great computer for what I needed it for. I returned this item 1/17/25 and today is 1/26/25 and I still haven’t received a refund.

Don’t order from this vendor
Sent me a starter that didn’t work. Then messaged me back only to say they don’t handle logistic related matters, they don’t have access to process exchange items and that I should just re order. Please don’t waste your time with this vendor! Now I’m stuck with a starter that doesn’t work!

Comparable to OEM and works on the first crank
This starter shape already mimics the original, meaning it should fit, and that it did! Installation was easy after removing the battery tray to get to it. Then remove the bolts from the starter and the connection then install and it took about 35 minutes to get it installed. We cracked it up and it started on the first start. Fit and functional is where the largest points are, and these are what makes this a good reliable starter. For the price it’s a great alternative to the dealer parts. So far the car is starting with no problems or issues.its construction is made of durable metal as it endures heat and cold cycles and to withstand rust and corrosion. It’s in par with the OEM and about the same weight.

Better than expected
I bought this thinking it was just like any other cabin air filter that fit my truck. It fits my truck perfectly. The Surprise was that it has a carbon filter side and is very well made. I can recommend this to you, and I will buy it again when it is time for a replacement.
