Remanufactured Ford Mazda 2.3L Cylinder Head Casting #6M8G

Premium OEM-Quality Replacement Engineered For Durability And Direct Fit

This professionally remanufactured 2.3L cylinder head (Casting #6M8G) is engineered to restore factory-level performance to your Ford or Mazda engine. Each unit is precision-machined to meet or exceed original equipment specifications, ensuring optimal sealing and long-term thermal stability.

🛠️ 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.

  • 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.
