DPR Import Street / Competion / Racing Port & Polished Cylinder Heads

Different stages of cylinder head development include special combination of porting and polishing, redirected ports, and multi-angle valve seats to full radius-blended valve seats. We don't use shortcuts, such as grinding and sandblasting combustion chambers, and our heads are meticulously, deshrouded and polished, Every head that comes to DPR is specifically built to the owner's needs (i.e., naturally aspirated, forced induction, nitrous oxide). As anyone with any automotive credibility realizes, when it comes to cylinder heads there is no such thing as "One Size Fits All". Don't settle for whatever is gathering dust on warehouse shelves! You deserve the best. You deserve a DPR cylinder head!
