IAG Performance IAG-ENG-H800E IAG 800 CNC Pocket Ported Comp Cyl Head - No Cams, Towers, Lifters or Rockers

The IAG 800 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 600 heads. These heads work great for cars with some race track duty (road, rally, auto-x, drag) and are designed to support up to 800 BHP with supporting mods. These heads include upgraded GSC +1mm Stainless Steel Valves, GSC Viton Valve Stem Seals, Upgraded GSC Valve Guides, Kelford Dual Valve Springs with Titanium Retainers, and OEM Keepers. FA20 Heads are configured differently from their EJ counterparts. In FA20 heads the casting is split into two parts, the "lower" and the "cam towers." As the name suggests, the "Cam Towers" hold the camshafts to the cylinder head. Kelford "A" cams are available with IAG 800 Cylinder Heads. When Kelford cams are chosen we also include new OEM cam towers, rockers, pivots, and valve shim caps.
