Show original supplier description
The Mazworx VQ37VHR Heads Stage 3 represent a significant upgrade for performance enthusiasts looking to maximize their VQ37VHR engine's potential. These cylinder heads are not merely modified; they are rebuilt and enhanced through a comprehensive Stage 3 package. The labor involved includes critical steps such as oil port plug modification, freeze plug replacement, and meticulous valve guide work, including removal, reinstallation, and reaming. The valve job is performed to race specifications, and valve lash is precisely set before the heads are resurfaced and assembled. Key components included in this package are Supertech intake valves sized +1mm larger, and Supertech Inconel exhaust valves also at +1mm. The valvetrain is further bolstered by Supertech bronze valve guides, a Supertech dual valve spring kit rated for 70lbs on the intake and 60lb on the exhaust side, and Supertech valve seals. Completing the performance enhancements are JWT C2 exhaust cams, featuring a 272 duration and 11.7mm lift. To complete the installation, core VQ37VHR cylinder heads are required. This build-to-order item comes with a complimentary t-shirt. The price for this stage of performance enhancement is $4,999.00.
