The IAG 750 CNC Pocket Ported Competition Cylinder Heads are designed with the weekend racer in mind. These CNC pocket ported heads provide a significant upgrade in flow over the IAG 550 heads. These heads work great for cars with some race track duty (road, rally, auto-x, drag) and are designed to support up to 750 BHP with supporting mods. These heads include upgraded GSC Standard Size Valves, GSC Viton Valve Stem Seals, IAG Stage 1 Valve Springs with Titanium Retainers, and OEM Keepers. GSC S1 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.
