Description

50 States Emissions Legal (E.O. D-701-38) 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 LB7 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, and heat and creep resistance, which prolongs the cylinder head's lifespan significantly.

PPE Cylinder Heads also share the same heat expansion rate as the stock cast-iron cylinder block no more blown head gaskets. PPE LB7 Cylinder Heads also feature cast-in fuel injector cups and solve the OEM injector cup leaking issue.

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.

Great for Indy Comic and Zine Covers
Size: 11"X17"
I use both the 11x17 and 8.5x11 Koala Glossy Inkjet papers as cover stock for Night Phoenix Press mini comics and zines, most often as Kickstarter add-ons or promo items. For that role, they deliver. The gloss finish immediately gives even short-run projects a polished, professional look with the other side having a matte finish which I can flip over for sketch covers using the matte side for the exterior cover. Colors print vibrant, blacks are strong, and the surface takes ink evenly without streaking. The finish looks clean enough to pass for offset printing on both inkjet and laser printers. This paper is also great for comic covers because it can fold down the middle without splitting the gloss coating too much if at all. The 8.5x11.5 works just as well for minis, one-shot zines or inserts. Between the two sizes, I can cover nearly every indie project format I need. They have just enough weight to feel like a true cover while still running smoothly through an inkjet printer. These books are often handled by backers or used as handouts, so durability matters. The stock holds up, though glossy paper can pick up fingerprints or light scuffs if stacked loosely. Bagging finished copies or boxing them quickly solves that. For the cost, it’s a dependable option that makes Kickstarter rewards and promo zines look far more professional than plain paper covers. For creators producing indie comics, add-ons, or zines on a budget, this paper is one of the easiest ways to elevate presentation without driving up printing costs. -Nathyn Brendan Masters

Ausurion products protection
Asurion is a great company to insure your products whenever you purchase items from online businesses like, Amazon. I had a portable hot spot device ordering from Amazon with a 3-year protection plan, unfortunately, the device has accidentally fallen and refused to turn on, then I went on Asurion Online website and filled in a claim and waited for approval to take that device for repair, luckily, they do not haven’t repaired shop services near me, they just refunded the original item price to me by Amazon Gift cards without knowing it few days than expected. I highly recommend Asurion for your product insurance needs.
