High-Performance Cast Iron Replacement For Naturally Aspirated Engines

Restore your engine’s peak efficiency with this premium pair of cylinder heads, specifically engineered for naturally aspirated GM 3800 engines. These heads are precision-machined to optimize airflow and ensure a perfect gasket seal, providing a durable and cost-effective solution for restoring lost horsepower.

🛠️ 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.
