Three Cylinder Head Build Options Available At Dieselpro.com

1. Bare Cylinder Heads

A bare head is ideal for customers who want to reuse many of their existing components or prefer to build the head themselves. Diesel Pro Power bare heads include:

• Precision-machined casting

• Cleaned, inspected, and professionally prepared surfaces

• Ready-to-install valve seats and injector tube locations

Bare heads are a preferred choice for:

• Experienced rebuilders

• Operations with in-house machine shops

• Owners reusing specific performance components

2. Cylinder Heads with Valves and Springs (Semi-Complete)

This option provides a ready-to-install valvetrain foundation without full rocker assembly components. These heads include:

• Valves installed

• Valve springs installed

• Keepers and retainers

• Fully machined and assembled valvetrain seating

This level is ideal for operators who want a turn-key valve setup but still prefer to install their own:

• Rocker arms

• Cam followers

• Valve bridges

• Push rods

Semi-complete heads reduce installation time while allowing customization.

3. Fully Complete Cylinder Heads

Diesel Pro Power also offers fully assembled heads containing:

• Valves and springs

• Valve bridges

• Rocker arms

• Cam followers

• Push rods installed and matched

This is the preferred option for:

• Marine operators needing fast turnaround

• Industrial or generator applications requiring minimal downtime

• Technicians who want a “drop-in ready” solution

• Fleet operators needing consistent engine performance

With a fully complete head, technicians can move directly to installation, saving hours of labor and removing the guesswork from assembly.
