5.7 HEMI Chamber
Looking to unleash the power of your 5.7 HEMI? Let us help! We now offer CNC Ported 5.7 HEMI heads and Comp Cams XFI Hydraulic roller cams. We don’t believe in stage I, stage II, and stage III porting jobs. We only offer max effort heads with top quality components. Some vendors use stock valves and valve springs on their ported heads. Why screw around with stock and stock style parts, when you can have the best for similar money? These heads will work great on stroker combos, as well as stock displacement engines. Check out these features:
- Fully CNC Ported intake and exhaust
- Race valve job
- One piece stainless valves 2.02/1.57
- PAC Beehive springs
- Titanium retainers
- Machined keepers
- Viton seals
5.7 HEMI Intake
- Surface milled to ensure head gasket sealing
- 81CC Chambers
- 190CC Intake Ports
Core or core fee required. Please allow up to 2 weeks delivery.
We also offer Comp Cam’s line of camshafts and Cometic gaskets to complement these heads!
