Katech CNC Porting Bundle L83 Cylinder Heads (PAIR)

NOTE: This CNC porting bundle is unique as it does not include CNC porting the intake and exhaust runners, but rather the chambers and a valve job and hand-blending. Flow testing indicated that porting the intake and exhaust runners on the L83 head did not net an airflow gain and actually hurt in some areas. In testing we found that CNC porting the chambers, a valve job and hand-blending netted significant airflow gains as indicated by the flow data sheet above.

 

This bundle includes:

Disassemble

Wash

CNC ported chambers

Competition valve job

Hand-blending

Cylinder head deburr service

Katech logo engraving

 

Note: Re-assembly and valve reconditioning not included.

 

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 car

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.
