DESCRIPTION

  • Increase RWHP Up To 35
  • Increases RW Torque Up To 35 For Stage III performance, changing to optimized cylinder heads is essential. Our ECPP Performance Heads are new, not an exchange head, for the "best" combination of perfected performance and value we've found. The port design is reconfigured with the aid of computer technology and then CNC machine ported to achieve 100% uniform performance and to assure flow is totally maximinized. Next, valve sizes have been increased to 2.02" & 1.57" on the intake and exhaust respectively to optimize air/fuel & exhaust flow. The combustion chambers are adjusted down to 62 cc's to increase the final compression ratio between 10.7 & 10.8. This modification, however, still allows the use of 93 octane pump gasoline. Additionally, new stainless steel valves, dual valve springs, titanium retainers, bronze valve guides & hardened valve spring seats are included. The new heads are assembled with a 5 angle valve job on the valves & the valve seats are radius cut with 2 angles. Our heads have been flow bench tested, dyno-tested & track tested to provide guaranteed "seat of the pants" results. The ECPP Performance Heads are new & do not need a core.
