Valve Flow TECH Tips . . .



The "Project 283" will benefit from improved flow after I back-cut the radius on the valve heads.  You can see that the valve on the left has the sharp edge removed.  I believe it's most important on the Intake Valves since the air is coming from the stem-side and into the cylinder.  The Exhaust Valve has the leading-edge on the head radiused, since the air is coming from the cylinder . . . out the exhaust pipes.
