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.
