Ford PRO1 CNC Heads |
|
Ford Pro1 series cylinder heads are based on dedicated castings which are fully CNC ported and have fully CNC'd chambers for maximum airflow and consistency.
Dart's Ford Pro 1 Cylinder Heads are cast from the same virgin C355-T61 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 compatability. Exhaust runners are raised 0.135" for improved flow. The exhaust flange uses the spread bolt pattern on CNC ported heads to accomodate headers. Manganese bronze valve guides are used for long life, and hardened valve seats provide durability with unleaded fuels. |
