CNC Circletrack Roller Head

CNC Circletrack Roller Head

Product Information
Let our 15+ years of race winning 2300 porting and head building experience put you in the winner's circle! There simply is nothing out there producing the flow and power our heads make, or offering the before and after sale customer service that we can. Only the highest quality components, 5axis CNC porting and modern machining practices go into your custom built head. Every head is meticulously ported, machined, cleaned, clearanced, setup and assembled with the utmost attention to detail . To simplify the ordering process, we have listed below our most common head assembly and upgradable options. Our head package below begins with a magnaflux tested crack-free factory iron D port closed chamber core, hardened exhaust seat inserts, new valve guides installed (diamond honed to size), Solid lifter conversion with tower straps, milling for high compression (CBN finish for MLS gaskets), Bo-port spec high flow valves, beehive valve springs, custom billet roller cam ground for your application, roller followers, lash set and ready to install on your short block. We recommend our stage 3 porting program for 2300cc engines up to 8000rpm and for 2500cc engines up to 7500rpm. Our stage 4 porting program is better suited for 2300cc engines turning 8500rpm or more and 2500cc engines (and larger) turning over 8000rpm. Both porting options' power potential is fully optimized with our matched CNC stage 4 intake manifold. Our stage 3 head with stage 4 .620" roller cam will typically dynotest at 220-230hp. Our stage 4 head with stage 5 .660" cam will support 240-260hp (with supporting components). Give us a call with any questions and we look forward to being a part of your racing program and helping put you out in front! 775-884-3000_____________________________________Please note- if supplying a core it must be received and inspected for cracks and damage before your new head ships.
