Nissan VK56 CNC Cylinder Head Porting | Pair
For Nissan VK56DE engines
This service is for CNC porting of the Intake & Exhaust runners only. You are expected to send heads in fully disassembled and clean.
Now you can get this porting service on your cylinder heads at an incredibly low cost! Simply follow this procedure:
Remove the cylinder heads from your engine
Disassemble cylinder heads to completely bare condition
Wash cylinder heads, heads must be free of carbon & oil
Print a copy of your order confirmation, put it in the box and send the heads to:
Katech Inc.
Attn: Cylinder Head Department
24324 Sorrentino Ct.
Clinton Twp., MI 48035
NOTE: Not including a copy of your order confirmation in the box will prevent or delay the processing of your order.
Please be sure to properly package cylinder heads with plenty of bubble wrap protection on the corners. We have found that when shipping cylinder heads a box, wrapped in bubble wrap, within another box offers the best protection from damage. Please do not use packing peanuts.
Includes Katech logo engraving
*"Expected to ship" time in the online store is an estimate based on receiving your cylinder heads within 5 days of ordering and may vary based on shop load.
*** This service requires the valve guides to be pushed up for porting and returned to their original position once the porting process is completed. Because of this we highly recommend a valve job to ensure valve to valve seat concentricity ***
