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.
