Our modified engines feature a multi angle valve job for increased head flow and performance. This usually entails placing different angles on the valve seat itself, increasing the flow of combustion gases and improving horsepower and torque. A multi angle valve job is the cutting or grinding of 2 or more angles on the seat and valve.
On most of our American engines we perform three angle/radius valve jobs. This is more applicable in the American iron heads and differs with some imports. We have seen most American cylinder heads benefit from a three angle radius valve job, but mostly because the American heads are so bad to begin with. Many American heads suffer from poor uneven castings right out of the box, so if performance is your goal, doing a multi angle valve job with bowl blending would be critical to your engines performance.
Our flowbench testing has proven time after time that the correct angles and angle widths is what's important. We found at Eddies that more CFM gains have been made through our special procedures of applying three angles or radiuses.
If your vehicle is a muscle car, classic car, street car or race car, Eddies will help you rebuild your engine using our 35 years of testing and flowbench work to build you the best engine possible. For more information,please visithttp://www.bossgoo.com
