Intake To Exhaust Valve Ratio. most common high performance heads utilize an exhaust valve diameter that is about 80% of intake valve diameter. Everyone agrees that they would go to a. i have a cyl head currently that the intake valve is maxed out (poor port that can't be made any larger), but there is room. intake valve (left) has a 30° back cut above the seat and a thin margin with a sharp edge on the bottom to discourage inlet tract reversion. Corresponding exhaust valve has a thicker margin to resist higher temperatures and a generous radius on the bottom to encourage exit flow around the valve. in this post, i discuss formulas for converting combustion chamber volumes, exhaust to intake ratios, valve curtain area, port crosssectional area, and various other factors. due to the amount of energy (heat) lost during the combustion process, a basic ratio of 75 to 80% exhaust flow/size to. the higher the compression ratio (or rather the expansion ratio), the more you can bias flow to the intake for power, since. the ratios that i’m looking at are the surface area of the intake to exhaust valve. the intake to exhaust size ratio changes, the intake to exhaust flow ratio needs to change and the exhaust port changes dramatically.
