 Butler Built and Blueprinted to same specs as the Edlebrock 61529 out of box cylinder

Performer RPM CNC cylinder heads have the same specifications as our popular Performer RPM Round Port cylinder heads for 1962-79 455 cubic inch Pontiac engines, but feature a CNC machined combustion chamber. The CNC machined chamber results in a consistent and precise chamber for improved flow performance & more efficient combustion. Performer RPM CNC cylinder heads are available in two chamber sizes. The 87cc chamber version is ideal for 10:1 engines and will deliver excellent street performance on low octane fuel. Performer RPM CNC cylinder heads with 72cc chambers are best for higher compression engines. Both are patterned after the same port flange configuration as the 1969-1970 Ram-Air IV Pontiac Round Port cylinder heads. EQUIPPED WITH SPRINGS FOR USE IN HYDRAULIC ROLLER CAMSHAFT APPLICATIONS


Cylinder Heads

Butler Performance offers many heads from today's top manufacturers such as Edelbrock and more. We only sell heads from names we trust that build high quality heads designed specifically for your application. Here at Butler Performance , we not only provide these heads in the box, but can customize then for your specific application.

Much like rotating assemblies, we do not leave anything to chance. All of our custom cylinder heads go through an extensive multi-step process to ensure they are up to the "Butler Standard". We provide many services such as hand or CNC porting. Our valve jobs are done using Serti equipment for ultra high precision valve seating and valve guides. This equipment is standard in high precision applications such as Formula One Racing and super high performance racing applications.
