All remanufactured cylinder heads are guaranteed to be free from defects in materials and workmanship. All automotive cylinder heads are guaranteed for six months, or 6,000 miles, whichever comes first. Cylinder head warranties are limited to replacement of defective head, gasket necessary to install.

Items not covered by the warranty include oil, oil filter, antifreeze and damages resulting from loss of time or usage of the vehicle. Original warranty is not extended as a result of repairs or replacement.

The warranty is void if the head exhibits signs of being overheated.

Warranty is also void if the head is warped as a result of heat or improper head bolt torque.In the event of a failure, please contact Midwest Cylinder Head and Machine immediately. All defective cylinder heads must be returned uncleaned. The cylinder head must be tagged and boxed. A completed warranty claim form and the original repair order must accompany the cylinder head.

3. What is your core deposit policy?
The customer will be billed a "Core Deposit" for any head we ship from exchange stock.

The core deposit will be refunded upon receipt of a like rebuildable head. If the core is unacceptable for remanufacturing, the customer will be given the option of sending another like core, or paying the core deposit. The core must be returned within 30 days from the date of invoice for full credit. Cores returned after 30 days of invoice will be refunded for casting value only.

4. Can any crack or damage be repaired?
In most cases, the answer is yes. Some things that can affect our ability to repair an item are:

Your head or block is made of "dirty" material. That means that the cast iron that your head or block is made from has many impurities in it. The new cast iron material that add to it will not bond to the original material. In other words, the weld will not stick.

The head is beyond machining limits. That means that the head or block has been surfaced too many times and would be too thin to properly compress the head gaskets if it were surfaced again. Or the head has been rebuilt many times and the valve seats are a large diameter. If we were to put the a larger diameter seat in the head, we would cut into the water cavities of the head. If that happened, than we would need to weld up the seat areas of the head and recut them for smaller seats. All that welding would cost so much that it probably be better to find another head that doesn't need so much welding.

5. Do you arc weld cast iron heads and blocks?
No. What we do is called 'oven fusion cast iron welding. The heads and blocks are slowly heated to the proper temperature in large ovens and are then welded with a torch and cast iron welding rod and flux. When the welding is done, they are slowly cooled overnight to avoid new cracks and to relieve internal stress in the welded item. All aluminum heads are tig welded only.

6. Why should I choose a welded head or block?
A head or block that has been repaired by welding costs less than a new or used one. If it is not a common engine, than there are many times when you cannot find a new or used one. Antique, obsolete engines, and parts are sometimes hard. or impossible, to find. In all cases, welded heads and blocks are as good as new and and many times they are even stronger than the original casting design.
