Product Description

Pro 1 CNC big block Chevy, 335cc intake runners, 121cc combustion chambers, 2.300 intake and 1.880 exhaust valve job, bare.

Every intake port, every exhaust port, every valve bowl and every combustion chamber is 100% CNC machined on special, dedicated Pro1 castings. Our 5-axis computer controlled machining centers produce compound curves and complex shapes with consistency.

Features:
- Premium alloy: Dart aluminum heads are cast from virgin 355-T61 aerospace alloy for superior strength and integrity.

- Bolt on compatibility: 2 degree rolled valve angle and standard spacing accommodates all stock accessories.

- Heart shaped 121cc chambers improve combustion efficiency.

- CNC machining ensures that every chamber has the same volume so that every cylinder maintains equal compression.

- Raised spark plug location improves flame travel for a quicker, more complete burn, producing more power.

- Multi-angle intake seats and radiused exhaust seats greatly improve air flow.

- Hardened exhaust seats are compatible with unleaded gasoline.

- Exhaust ports raised .300" to improve flow (requires 1" longer head bolts next to exhaust ports).

- Spark plug holes are machined for gasketed 3/4" reach plugs.

- Manganese bronze valve guides ensure long term reliability.

- All cylinder heads sold individually.
