All Cylinder Heads, Blocks, and Crankshafts have a core charge. The core charge is present to be sure that our stock of "cores" stays current and full. Our current policy is as follows any customer purchasing a cylinder head, block, or crankshaft will be charged the current core rate, this rate varys according to the model of said item. The core charge will be refunded back if the buying customer wishes to send in the exact item (example purchasing a Chrysler 2.2L cylinder head. The customer will then send in the corresponding item in this case a Chrysler 2.2L cylinder head.) If this is done and the "core" exchange meets all standards to be remanufactured a refund will be issued via check to the confirmed shipping address and buyer. If there are any questions regarding this policy please email or call toll free 1-800-873-8506.
