For those who are installing this cylinder head, it is strongly recommended that a plug kit be purchased, if you do not already have one. We offer several inexpensive plug kits that will make the process easy. Be sure to also change the gaskets every time the cylinder head is removed from the rest of the engine. We offer several gasket kits that will include all of the gaskets and seals that you will need.

For a Detroit Diesel 6-71 or 12V71 engine, the performance of the cylinder head can make the combustion chamber behave like a well-orchestrated symphony. When this part goes bad, the entire engine can behave erratically, or not function at all. That is why, if you want your classic 6-71 engine to keep performing like it should, it needs a cylinder head that can also perform. At Diesel Pro, we make parts that last, and offer a comprehensive collection of Series 71 engine parts, as well as many other parts for Detroit Diesel engines.
