Cylinder Porting Modifications

Back to Services

We provide competition level cylinder head work that's known for producing considerable horsepower gains. The often amazing performance we're able achieve is the result of constant development, refinement, racing and verification through our own Dyno testing. We can do anything from a Supersport valve job to building a fully developed Superbike head and most everything in between. Each cylinder head is different, requiring evaluation and development on an individual basis for best results. Everyone we build for competition is optimized for our customer's specific application and needs. 2008 ported heads from our technician was used with the Kawasaki Attack race team that came 1st and 2nd at Daytona 200

Below, you'll find the general type and range of work we do. The detail and extent of work depends on what's required for optimum results. Cylinder head work intended for racing requires an initial consult, to provide the best possible setup for your specific application and needs.
 

SUPERBIKE CYLINDER HEAD DEVELOPMENT

Detailed inspection and analysis
Replace valve stem seals
Replace worn parts (near or at service limit)
Optimize / reconfigure - intake & exhaust ports - geometry/profile/finish
Match - intake boots & exhaust flanges (or gasket) to ports
Optimize /equalize - combustion chamber geometry
Match / open - combustion chamber to custom valves/pistons (as needed)
Optimize / reconfigure - valve seat geometry (S-angle to full-blend seat cut)
Optimize / reconfigure - valve geometry (machine as needed or design new valves)
Deburr / radius - camshaft journals/holders/followers (reduce wear/frictional losses)
Deburr / radius - camshaft oil feed passages (improve lubrication properties)
Optimize - compression ratio (machine surface as needed)
Pro assembly
 

PRODUCTION - SUPERSPORT CLASS

Legal for AMA Supersport/Superstock and AFM Production as well as most other production based racing classes (road or drag). Cylinder heads are built to maximize performance while complying with the rules. Service methods are listed for your reference, in addition to the key benefits

Detailed inspection and analysis
Replace valve stem seals
Replace worn parts (near or at service limit)
Combustion chambers - cleaned via media blasting with valves in place
Intake & exhaust ports - cleaned via manual/chemical means (Without media blasting)
Deburring - limited to machined edges to max allowable of 0.50 mm (.020")
Optimize / reconfigure - valve seat geometry (S-angle to full-blend seat cut)
Optimize - compression ratio (machine surface as needed)
Pro assembly
 

STREET APPLICATION (NON EPA/CARB COMPLIANT)

Perfect for street riders who occasionally go to track days and/or the drag strip. Designed for a good balance of overall power gains and service life. This service provides increased mid-range power and responsiveness with moderate top-end gains. Here's a list of the key benefits.

Detailed inspection and analysis
Replace valve stem seals
Replace worn parts (near or at service limit)
Rework - intake & exhaust - bowl/throat/roof/short-side radius
Match - intake boots & exhaust flanges (or gasket) to ports
Unshroud / blend - valve pockets
Deflash / blend - combustion chambers
S-angle or full-blend seat cut
Optimize - compression ratio (machine surface as "needed)
Pro assembly
