King Motorsports Head Porting & Valve Job - Ultra Build

The Ultra Performance Head Port and Valve Job includes every WHP increasing trick we have up our sleeve. Although streetable, this option is most often used in high-HP race engines.  Custom-tailored for your specific application, we configure this option to not only your internals, but to the specific use; ie strip, track or street. It begins with disassembly, inspection and cleaning. Now begins the porting - shaping the ports and chambers to produce maximum performance based on what cams and valves you're using. The valves may be faced and/or back cut. The valve seats are then cut with a multi-angle grind, the valves are lapped and the valve seals are replaced. All valves are vacuum-checked. Your head and block are milled to achieve the correct compression, chamber shape and squish, as well as piston top to deck depth or protrusion at TDC. All internals will be reused unless damaged or worn. Any parts needing replacement (excluding valve seals) will be extra, but you will be informed of any damaged parts before we continue. Your free-breathing head is then completely assembled using Redline Assembly Lube.

The flowcharts below show the sustantial gains obtained with our Ultra Performance Porting and Valve Job.
