Stage 2 is what we base our naturally aspirated racing heads on. Bronze liners give us a better than stock valve guide for performance applications, and the stainless valves greatly improve the flow potential.
- A cleaned, baked, blasted, and pressure tested set of heads
- Machined deck surface good for an MLS head gasket (or stock).
- Port matched, reshaping, polishing, and blending to give the best flow
- Stainless valves, modified for flow. 1.8"/1.42"
- Reconditioned valve guides with bronze liners. Sized to spec clearance with the new valves.
- 5 angle valve job on the intake seat, 3 angle valve job on the exhaust, 2 angles on the valves
- LS Style Seats and seals
- Comp 26915 Valve Springs
Options
- Time-Sert for Rocker Arm Bolts. This is a useful upgrade for the 8mm rocker arms used after 2002. While not common, there have been rockers that get stripped out of the heads. This option will eliminate the possibility.
- CBX Thermal Coating for combustion chamber and valve faces. Great for motorsports applications, this coating will help keep the heat in the exhaust rather than being absorbed into the piston and cylinder head.
