Description

Built for ported heads and real track work, the GSC R2 profile drives the GT350 Voodoo Flat-Plane hard to 8,300 rpm with a usable band from 6,000–8,500 rpm.

Events are modeled for Voodoo heads flow behavior and correct rocker geometry for high-flow combinations, then cut from our U.S.-made forged billet blanks and finished with BLACK ISE for reduced friction and long life. Runs on pump gas, race fuel, or ethanol blends (E85/E90).

Install notes

  • Clearance: Always verify piston-to-valve clearance with your exact heads, pistons, and gasket stack. With OEM pistons and deck heights, the full phaser range is typically usable without clearance issues.
  • Use upgraded valve springs (and Ti retainers) set to the tuner’s rev limit; check installed height and coil bind.

Specifications

  • FuelPump / Race / E85–E90
  • RPM Band 6,000–8,500 rpm (≈8,300 peak)
  • Valve Springs Upgrade required (GSC springs + Ti retainers)
  • Use Case OEM or Ported Head Race Profile — track-focused
  • Head Type OEM/Ported heads (high-flow)

Product Details
