Heads
Corvette heads are a product of their own due to the construction of the heads and the flow abilities from each valve setting design. GM has continued to improve on the head design. The basic Corvette cylinder head design of the LS9 is similar to the high performance L92-type head found on the LS3 V-8, but it is cast with a premium A356T6 metal alloy that is better at handling the heat generated by the powerful supercharged engine – particularly in the bridge area of the cylinder head, between the intake and exhaust valves which is an important area.
In addition to the special aluminum alloy, each head is created with a roto-cast method. Also known as spin casting, this unique process involves pouring the molten alloy into a computer controlled rotating mold. This makes for more even distribution of the material and virtually eliminates all porosity – any air bubbles or pockets that may be trapped in the casting – for a stronger finished product.Although these heads are based on the L92 design, they feature swirl-inducing wings that are also cast into the intake ports. Another process that improves the mixture motion of the pressurized air/fuel charge. The charge enters the combustion chambers via titanium intake valves that measure 2.16 inches (55 mm) in diameter. Spent gases exit the chambers through 1.59-inch (40.4 mm) hollow stem sodium-filled exhaust valves. The titanium intake and sodium-filled exhaust valves are used for their lightweight and high-rpm capability.
