New GM Chevrolet 4.3L V6 Cylinder Head – 113 Casting

Premium OEM-Quality Replacement Cylinder Head

This brand-new cylinder head is engineered for GM 4.3L V6 engines featuring the #113 casting. It comes fully loaded with valves and springs to ensure a seamless, direct-fit installation for both automotive and marine applications. Designed to meet or exceed OEM specifications, this head provides the durability and performance needed for long-term engine reliability.

🛠️ In-House Machining Process

Cleaning: Fully disassembled and thermally cleaned.
Soda Blasted: Castings are blasted with Sodium Bicarbonate. Because baking soda is water-soluble, there is zero risk of abrasive media clogging oil passages.
Pressure Testing: Tested to 60 PSI to ensure no cracks or porosity leaks.
Surfacing: All heads are resurfaced on our Rottler S85A for a precision gasket-sealing surface.
Valve Job: Multi-angle valve job performed; every port is Vacuum Tested to ensure valves are seated 100% airtight.
