OverviewSpeedmaster LS-series cylinder heads are rapidly expanding. The LS (Gen3/4) platform has many design benefits over the earlier SBC engine designs, most notably the cylinder heads. Although the GM heads are good pieces, We have developed a superior line of heads for modern performance enthusiasts. Like all Speedmaster cylinder heads, the LS-series heads are produced using our "Gravity Casting" process. This process ensures a more uniform and robust casting, laying a strong platform to build on.SpecsBrand: SpeedmasterPart Number: PCE281.2090Part Type: Cylinder HeadProduct Line: Hydraulic Roller TappetCylinder Head Style: AssembledCylinder Head Material: AluminumCylinder Head Finish: NaturalCombustion Chamber Volume (cc): 68 ccCNC-Machined Combustion Chamber: NoIntake Runner Volume (cc): 198 ccExhaust Runner Volume (cc): n/aCNC-Machined Intake Runner: NoCNC-Machined Exhaust Runner: NoIntake Port Shape: CathedralIntake Port Location: StandardExhaust Port Shape: OvalExhaust Port Location: StandardSpark Plug Style: OEMComp.
