Just picked up a set of Vortec heads(906)and was curious if anyone had flow #s on them with 1.94/1.50 valves, and 2.02/1.60 valves. I have heard that they are very good flowing heads to start with. I have changed them to 2.02/1.60 valves. Also, has anyone ported these heads? What kind of flow #s did you get when they were ported. If you could give me a chart all the way up to .600 lift would be great. Thanks for any help.
