Understanding LS Heads

LS cylinder heads were the most powerful and advanced cylinder heads introduced by General Motors. They were lightweight, made from aluminium, and designed to bolt up to LS engines. The power of these LS cylinder heads can be determined by the fact that they feature 259 CC intake and 102 CC exhaust runners. There were also 72 CC combustion chambers and 2.1 65" intake, and a 1.600" exhaust valve. The design is created in such a way that LS heads can assemble easily with valve springs, retainers, locks, guide plates, studs, and even seals. The outcome of this design was the benefits like economic availability yet maximum output. There were ported heads also mainly designed and produced in the form of fully assembled and heavy-duty components.

These LS cylinder heads are compatible with most of the LS series engines manufactured by General Motors, and one of them is the LS7 engine. This engine comes with some high-end engine specifications like –

Unique High-Flow

CNC-Ported

Square Port

Cylinder heads and intake are manifold in this series

Intake valves are made up of titanium

1.8 ratio rockers are present

The camshaft has a really long-duration high lift

Deck plates are used for block machining performing to increase accuracy

The oiling system is of a really high capacity and dry sump

When all these features combine with the power of versatile LS heads, they can make an LS engine generate a whopping capacity of 7100 RPM.

How to Install LS Cylinder Heads?

The first recommendation here is to rely upon highly established car mechanics for the same. They will follow a step-by-step approach for the installation procedure and ensure that an oil and coolant leak situation does not occur. Here is the detail of the installation process followed for installing LS cylinder heads.

Step – 1

The first step is to press new dowel pins into the engine blocks. There are two dowel pins per side in holes 7 and 8. They have to align the head to the block and this has to be done without fail before installing cylinder heads. To align the dowel pins perfectly, the team might have to tap them gently with a hammer.

Step – 2

Step 2 will involve cleaning the deck surface and placing the head gasket on the block while making sure that the appropriate direction is chosen.

Step - 3

Again the deck surface of the LS head will have to be cleaned using a clean cloth and acetone, and then, the cylinder head is carefully placed on the head gasket.

Step - 4

Now it's time to install the bolt fingers really tight and when done, the task of LS 3 heads and LS1 heads installation is over.
