Complete Dart Pro 1 Small Block Ford CNC ported cylinder heads part # 13071123 or 13072143

Ford Pro 1 CNC Ported cylinder heads are based on dedicated castings which are fully CNC ported and have fully CNC ported chambers for consistency and maximum air flow

Dart Ford Pro 1 cylinder heads are cast from the same virgin 355-T6 aircraft alloy that is used in Dart Pro-Stock heads. These Windsor style heads are available with CNC machined or as-cast ports.

Standard valve angle and spacing is retained for bolt on compatibility. Exhaust runners are raised .135 for improved flow. The exhaust flange uses the spread bolt pattern on CNC ported heads to accommodate headers.

Manganese bronze valve guides are used for long life, and hardened valve seats provide durability with unleaded fuels.
