The IAG 950 CNC Ported Race Cylinder Heads are designed for racing and competition. These fully CNC ported heads provide a significant upgrade in flow over the IAG 750 heads. These heads work great for cars where getting more power might be the difference between winning or losing that big race. The IAG 950 heads work great for drag racing, as well as high horsepower time attack or hill climb, and are designed to support up to 950 BHP with supporting mods. These heads include upgraded GSC +1MM Superalloy Valves, GSC Viton Valve Stem Seals, Upgraded GSC Valve Guides, IAG-Spec Beehive Valve Springs with Titanium Retainers, and OEM Keepers. GSC S2 Camshafts are available with OEM valve lifter buckets. We also offer an optional chamber modification service (see below) for EJ20 heads to allow use on EJ25 short blocks. Each IAG 950 Cylinder Head Set starts with new OEM castings from Subaru of America.
