Cylinder Head Port & Polish
Porting and polishing of the cylinder heads intake and exhaust runners, bowl area, short turn area and combustion chamber are the main keys in cylinder head power. A factory cylinder head off a common engine is cast, cleaned, assembled with valves, springs, seals and locks then is assembled onto the automobiles engine. I take the factory or high performance "Hop Up" head and port and polish it for maximum power.


Racing Valve Job
A valve job consists of boiling (cleaning) the head(s),checking the valve guides to see if they are good or need to be replaced. Replace guides if necessary then the valve seats which are part of the valve seat ring are cut on a 3 angle or radius (radius is usually done on the exhaust seat). The valves are then glass beaded and cut on the proper angle accordingly. The heads main mating surface is then checked and a clean mill is taken if necessary. After getting a valve job and/or a porting and polishing job, the heads are then cleaned again for final assembly. The heads are then assembled with the stock valves or aftermarket valves of your liking, stock or aftermarket valve springs, new seals and your locks and retainers which may be replaced to your requirements. Also included is checking each installed height of spring and tension of each valve spring. Going back to the flow bench results this is were they come in handy. Knowing were your heads flow It will help you pick out your camshaft and valve springs. Increasing CFM throughout the heads entire range of lift is more important than a max flow number. For instance a head that may flow 325 CFM at .650" lift which being its most flowing area, may under perform a head that flows 25CFM less at .650" lift but has a higher average CFM through out the entire range being .000" to .650".
