Cylinder Head Math for Engine Performance
WebA flow bench is used to measure the intake and exhaust airflow of a cylinder head. A typical cast-iron Pontiac D-port measures 190 to 210 cfm of peak intake airflow at 28 inches of pressure. Most aftermarket aluminum castings flow anywhere between 260 and 330 cfm. Specialized castings can flow more than 400 cfm. WebSep 1, 2024 · The valve size is 2.200˝ on the intake and 1.800˝ on the exhaust. The intake seats will allow 2.300˝ diameter valves to be cut in with valve to valve still adequate for the big cam grinds. It will support bore sizes from 4.125˝ to 4.500˝.
