🛠️ 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.
