Ls3 Cylinder Head Cam Intake Swap Combustion Chambers
|
The ports and combustion chambers on the Mast heads are fully CNC machined prior to shipment. Flatting out the valve angle from 15 to 12 degrees not only helps de-shroud the valves, but it also yields a smaller, more efficient, and faster-burning combustion chamber design. Customers have the option of choosing between solid- and hollow-stem steel valves, and our test heads were fitted with the latter. View Related Article
