New GM Mercruiser Marine Industrial Forklift 2.5 3.0 OHV Iron Cylinder Head – Large Port | 2776954

New GM Mercruiser Marine Industrial Forklift 2.5 3.0 OHV Iron Cylinder Head – Large Port | 2776954

Boost your engine’s power and corrosion resistance with this high-nickel, large-port iron cylinder head, specifically engineered for demanding marine and industrial environments.

This is a brand-new, heavy-duty iron cylinder head designed for GM 2.5L and 3.0L OHV engines. Featuring a Large Port design for optimized airflow, this head is cast with a higher nickel content to provide superior strength and exceptional resistance to saltwater corrosion—making it the ultimate choice for Mercruiser engines and industrial forklifts.

🛠️ In-House Machining Process

• Debris-Free Preparation: Every new casting is chemically cleaned and blown out to remove all residual machining oils and manufacturing debris. This ensures your engine’s oiling system remains uncontaminated from the first start-up.
• In-House Precision Machining: Unlike “shelf-stock” heads, we perform all final machine work in-house. This includes final guide sizing and precision valve seat cutting to ensure perfect geometry and clearances before the head reaches the assembly bench.
• Pressure & Integrity Testing: To go beyond the factory standard, we pressure-test every head to 60 PSI. This verifies that the casting is free of porosity leaks or internal defects that could compromise the cooling system in harsh environments.
• Dimensional Inspection: Our technicians perform a multi-point inspection of the gasket-sealing surface and bore alignment. This ensures the head is perfectly flat and meets tight OEM tolerances for a flawless fit.
• Professional Assembly & Setup: Valvetrain components are installed and verified in a clean-room environment. We check spring heights and seal seating to ensure the assembly is balanced and ready for high-performance industrial or marine use.
• Vacuum-Seal Verification: Every intake and exhaust port is Vacuum Tested. This guarantees a 100% airtight seal between the valves and seats, ensuring maximum compression and peak performance right out of the box.
