IAG Performance IAG-ENG-H950DL IAG 950 CNC Ported Race D25 Cylinder Head - GSC S2 Cams & Kelford Bucket Lifters

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 Kelford DLC Coated 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. The first step is to select your Year and Model of vehicle so that we may provide you with the right castings to fit your project. Next, you'll select whether or not you want to include our optional GSC camshaft package. If selected, these heads will include new GSC S2 Camshafts and Kelford DLC Coated valve lifter buckets for valve adjustment. To get the most out of these heads you'll want to select the GSC Power-Division billet S2 camshafts for your IAG 950 Head Package. These cams are built to suit the higher horsepower these heads will support. With a power range of 500 WHP and up, you need some additional supporting mods to utilize the true potential of the S2s. Our IAG 950 Short Block, an upgraded turbocharger and fuel system, and a quality engine management system are key. Along with the camshafts we'll include all new OEM valve lifter buckets and set bench lash using our specially designed fixture.
