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:
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 laser etched on both ends
