At BluePrint Engines,we realize how important it is to find parts that will fit your new engine! With headers, it’s crucial to understand that most aftermarket cylinder heads are designed for both performance  and efficiency. For this reason, BluePrint Engines cylinder heads (and most other aftermarket aluminum heads) are NOT direct clones of OEM iron heads. If they were, they would not make the horsepower we have come to know and love. However, many aftermarket headers are designed primarily around stock vehicles with stock heads. There are many “off-the-shelf ” headers that do work, but with the countless manufacturer SKU’s out there, we cannot guarantee every header fits our engines. For this reason, we have partnered with the header manufacturers below and shipped them our head castings so they can help you directly and confirm header fitment for your new BluePrint Engine in your specific vehicle. Please contact these companies DIRECTLY and let them know you have a BluePrint Engine before ordering! DO NOT assume that every part number from these companies will work for your application. You MUST CONTACT THEM DIRECTLY and make it known you have a BLUEPRINT ENGINE!
