They are designed to offer many of the features of other high-end cylinder heads at a more affordable price. Dart produces these heads from premium, high-density cast iron with extra-thick decks for durability and power potential. These heads feature precision-cast 165cc intake ports and heart-shaped combustion chambers that are designed to produce great airflow without expensive or time-consuming porting. The hardened exhaust valve seats are fully compatible with unleaded fuels, and the multi-angle intake and radiused exhaust seats further improve flow, maximizing power. Dart utilizes screw-in rocker studs that won't pull out, even under heavy use, and the machined valve cover rails eliminate possible oil leaks. All you have to do is choose which combination of combustion chamber volume and valve size will best complement your engine, and whether you want fully assembled, bolt-on heads or bare, ready-to-build castings. Dart Iron Eagle S\/S cylinder heads produce great throttle response and gains in low-to-midrange torque, just where you need it, for your street hot rod, musclecar, or pickup.\u003c\/p\u003e\u003cp\u003eCombustion Chamber Volume (cc): 67\u003cbr\u003eIntake Runner Volume (cc): 165cc\u003cbr\u003eExhaust Runner Volume (cc): 65cc\u003cbr\u003eCylinder Head Style: Assembled\u003cbr\u003eCylinder Head Material: Cast iron\u003cbr\u003eIntake Port Shape: Rectangular\u003cbr\u003eIntake Valve Diameter (in.): 1.940 in.\u003cbr\u003eCNC-Machined Combustion Chamber: No\u003cbr\u003eCNC-Machined Intake Runner: No\u003cbr\u003eCNC-Machined Exhaust Runner: No\u003cbr\u003eCombustion Chamber Style: Heart\u003cbr\u003eIntake Port Location: Standard\u003cbr\u003eExhaust Port Shape: Square\u003cbr\u003eExhaust Port Location: Standard\u003cbr\u003eSpark Plug Style: Straight\u003cbr\u003eIntake Valves Included: Yes\u003cbr\u003eExhaust Valves Included: Yes\u003cbr\u003eExhaust Valve Diameter (in.): 1.500 in.\u003cbr\u003eValve Springs Included: Yes\u003cbr\u003eMaximum Valve Lift (in.): 0.510 in.\u003cbr\u003eCamshaft Style: Hydraulic flat tappet\u003cbr\u003eOutside Diameter of Outer Spring (in.): 1.250 in.\u003cbr\u003eDamper Spring Included: No\u003cbr\u003eNumber of Springs Per Valve: Single\u003cbr\u003eRetainers Included: Yes\u003cbr\u003eRetainer Material: Steel\u003cbr\u003eLocks Included: Yes\u003cbr\u003eLock Style: 7 degree\u003cbr\u003eValve Stem Seals Included: Yes\u003cbr\u003eValve Stem Seal Style: Positive stop\u003cbr\u003eRocker Arm Studs Included: No\u003cbr\u003eRocker Arms Included: No\u003cbr\u003eRocker Arm Nuts Included: No\u003cbr\u003eGuideplates Included: Yes\u003cbr\u003eValve Cover Mounting Style: Centerbolt\u003cbr\u003eAccessory Bolt Holes Drilled: Yes\u003cbr\u003eIntake Valve Angle: 23\u003cbr\u003eExhaust Valve Angle: 23\u003cbr\u003eValve Guides Included: Yes\u003cbr\u003eValve Guide Material: Manganese bronze intake\/Phosphorous bronze exhaust\u003cbr\u003eValve Seats Machined: Yes\u003cbr\u003eValve Seat Machine Style: 4-angle intake\/3-angle exhaust\u003cbr\u003eValve Seat Material: Ductile iron\u003cbr\u003eCylinder Head Color: Natural\u003cbr\u003eSteam Holes Drilled: No\u003cbr\u003eOiling Style: Through pushrod\u003cbr\u003eMachined for O-Ring: No\u003cbr\u003eHeat Crossover: Yes\u003cbr\u003eRemanufactured: No\u003cbr\u003eQuantity: Sold individually (one head)\u003c\/p\u003e","brand":"Dart","offers":[{"title":"Default Title","offer_id":44878276886839,"sku":"DACH10024370A","price":1775.5,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0680\/9364\/1015\/files\/340538.jpg?v=1780399527","url":"https:\/\/enginemaster.com.au\/products\/dart-dach10024370a-iron-eagle-ss-cylinder-heads-chev-vortec-assembled-pair","provider":"Engine Master","version":"1.0","type":"link"}
