They feature 100 percent CNC-ported combustion chambers, CNC-ported exhaust ports, and CNC-ported intake ports. They are a conventional direct bolt-on, non-raised runner intake port configuration. AFR 245CC Eliminator heads share identical valve centerlines and rocker stud locations to the SBC 227 and 235 product lines. Larger diameter 3\/8 in. pushrods will fit without additional clearancing. They also come standard with a 3\/4 in. deck, 2.125 in. intake, and 1.600 in. exhaust valves. AFR 245cc NPP SBC Eliminator Racing cylinder heads are available bare or assembled and represent one of the best flowing 23 degree heads to date.\u003c\/div\u003e    \u003c\/td\u003e   \u003c\/tr\u003e  \u003c\/tbody\u003e \u003c\/table\u003e \u003cbr\u003e\u003cbr\u003e\u003ctable\u003e  \u003ctbody\u003e   \u003ctr\u003e    \u003ctd\u003e    \u003cp\u003eApplication: Chev Small Block Gen I\u003c\/p\u003e     \u003cp\u003eCylinder Head Style: Assembled\u003c\/p\u003e     \u003cdiv\u003eCylinder Head Material: Aluminum\u003c\/div\u003e     \u003cdiv\u003eCylinder Head Finish: Natural\u003c\/div\u003e     \u003cdiv\u003eCombustion Chamber Volume (cc): 80\u003c\/div\u003e     \u003cdiv\u003eCNC-Machined Combustion Chamber: Yes\u003c\/div\u003e     \u003cdiv\u003eIntake Runner Volume (cc): 245cc\u003c\/div\u003e     \u003cdiv\u003eExhaust Runner Volume (cc): 80cc\u003c\/div\u003e     \u003cdiv\u003eCNC-Machined Intake Runner: Yes\u003c\/div\u003e     \u003cdiv\u003eCNC-Machined Exhaust Runner: Yes\u003c\/div\u003e     \u003cdiv\u003eCombustion Chamber Style: Heart\u003c\/div\u003e     \u003cdiv\u003eIntake Port Shape: Rectangular\u003c\/div\u003e     \u003cdiv\u003eIntake Port Location: Standard\u003c\/div\u003e     \u003cdiv\u003eExhaust Port Shape: Square\u003c\/div\u003e     \u003cdiv\u003eExhaust Port Location: Raised\u003c\/div\u003e     \u003cdiv\u003eSpark Plug Style: Angle\u003c\/div\u003e     \u003cdiv\u003eIntake Valves Included: Yes\u003c\/div\u003e     \u003cdiv\u003eIntake Valve Diameter (in): 2.125 in.\u003c\/div\u003e     \u003cdiv\u003eExhaust Valves Included: Yes\u003c\/div\u003e     \u003cdiv\u003eExhaust Valve Diameter (in): 1.600 in.\u003c\/div\u003e     \u003cdiv\u003eValve Springs Included: Yes\u003c\/div\u003e     \u003cdiv\u003eMaximum Valve Lift (in): 0.800 in.\u003c\/div\u003e     \u003cdiv\u003eOutside Diameter of Outer Spring (in): 1.550 in.\u003c\/div\u003e     \u003cdiv\u003eDamper Spring Included: Yes\u003c\/div\u003e     \u003cdiv\u003eNumber of Springs Per Valve: Dual\u003c\/div\u003e     \u003cdiv\u003eRetainers Included: Yes\u003c\/div\u003e     \u003cdiv\u003eRetainer Material: Chromoly steel\u003c\/div\u003e     \u003cdiv\u003eLocks Included: Yes\u003c\/div\u003e     \u003cdiv\u003eLock Style: 10 degree\u003c\/div\u003e     \u003cdiv\u003eValve Stem Seals Included: Yes\u003c\/div\u003e     \u003cdiv\u003eValve Stem Seal Style: Positive stop\u003c\/div\u003e     \u003cdiv\u003eRocker Arm Studs Included: No\u003c\/div\u003e     \u003cdiv\u003eRocker Arms Included: No\u003c\/div\u003e     \u003cdiv\u003eRocker Arm Nuts Included: No\u003c\/div\u003e     \u003cdiv\u003eGuideplates Included: No\u003c\/div\u003e     \u003cdiv\u003eValve Cover Mounting Style: Perimeter bolt\u003c\/div\u003e     \u003cdiv\u003eAccessory Bolt Holes Drilled: Yes\u003c\/div\u003e     \u003cdiv\u003eIntake Valve Angle: 23\u003c\/div\u003e     \u003cdiv\u003eExhaust Valve Angle: 23\u003c\/div\u003e     \u003cdiv\u003eValve Guides Included: Yes\u003c\/div\u003e     \u003cdiv\u003eValve Guide Material: Bronze\u003c\/div\u003e     \u003cdiv\u003eValve Seats Machined: Yes\u003c\/div\u003e     \u003cdiv\u003eValve Seat Machine Style: 5-angle\u003c\/div\u003e     \u003cdiv\u003eValve Seat Material: Steel\u003c\/div\u003e     \u003cdiv\u003eSteam Holes Drilled: No\u003c\/div\u003e     \u003cdiv\u003eOiling Style: Through pushrod\u003c\/div\u003e     \u003cdiv\u003eMachined for O-Ring: No\u003c\/div\u003e     \u003cdiv\u003eHeat Crossover: No\u003c\/div\u003e     \u003cdiv\u003eQuantity: Sold as a pair.\u003c\/div\u003e     \u003cdiv\u003eNotes: Designed for large displacement small blocks.
