4P K24Z-R40 CNC Cylinder head will have CNC machined intake ports.  The exhaust is also CNC ported to improve flow.  We will be leaving areas of the exhaust port untouched where they are thin and prone to cracking with high exhaust temperature.  These heads have a lot of water running through the integrated exhaust manifold, so we will be porting the bowl area and exhaust outlet area where we can improve flow the most.  All heads will receive everything below....



  • Jet Wash and Soda Blast

  • Crack check and inspection

  • CNC Porting of Intake and Exhaust ports (CFM is drastically improved!!)

  • Newen CNC single point performance valve job

  • Surface

  • Assembly

  • This pricing is based on you sending your head in for porting and service. If you would like to purchase a core from us rather than send yours in, simply then select that in the options.


You can select options below and we will include those items on your Paypal invoice.  You can make payments to that invoice during the pre-order wait time.  We do have a new Ferrea spring kit available that has not previously been available to this platform.
