Industrial Cylinder Heads

Heavy Duty Industrial Cylinder Heads

The single most common source of engine failure is the heads.  The Industrial Cylinder Head provides increased protection for dry fuel applications. It helps the engine handle wider fluctuations in fuel quality.  It has greater mass where it is needed to help dissipate heat. It increases durability and provides additional resistance to cracking.

Intake (Industrial Cylinder Heads)


• Larger port provides greater air flow than the General Motors™ Head, resulting in more horsepower at higher RPMs.


• Threaded rocker stud does not penetrate intake port like the General Motors™ Head, avoiding potential issues with sealing.  When the “pressed in” rocker stud on the General Motors™ Head does not fully seal, oil will be pulled from the rocker arms and valve covers into the intake ports, creating oil consumption that is almost impossible to locate.


• .385” fire deck thickness has 38% greater mass than the General Motors™ Head, also providing more effective heat transfer away from the valve seat.


• Intake valve seat pocket depth is almost 10% larger, absorbing & dissipating heat more effectively.  Deeper valve seat pocket allows for a thicker, more robust valve seat.

Exhaust (Industrial Cylinder Heads)


• This is where heat dissipation matters the most.


• Threaded rocker stud more robust than “pressed in” rocker stud in the General Motors™ Head.


• .3825” fire deck thickness has 50% greater mass than General Motors™ Head, transferring heat more efficiently from the valve seat.


• .346” Exhaust valve seat pocket is 36% larger than General Motors™ Head, transferring heat more efficiently from the valve seat
