This increases air speed and flow over a 3-Angle Valve Job. A 5-Angle Radius Valve Job creates the best flow possible by adding additonal angles and a radius. The area around the valve seat is the most critical area of a port. Hi-Performance 5-Angle Radius Valve JobĪ RT Hi-Performance 5-Angle Radius Valve Job adds horsepower without sacrificing reliability. Superior Sealing equals More Power - Every head is Vacuum Tested and only passes if the sealing leakdown is better than 1%.Ī Standard 3-Angle Valve Job maintains factory designed flow and horsepower. RT Valve Jobs have guaranteed concentricity of better than. Outstanding Concentricity - It is common for stock heads to have. Race Tech uses a Rottler SG7 to provide a dependable, accurate, highest quality valve job. With years of using nearly every valve cutting tool available, Race Tech selected the Rottler SG7 as the best machine for high quality, precision valve jobs.Ī precision Valve Job is the core of a high-output, reliable engine.
