http://www.classicinlines.com/alum_img.asp The Ford 300 head I believe is going to be a better head ,as far as flow.
W/the 200 CI/smaller Ford sixes, cyl head, they limited them selves to being able to use stock type headers ,which is a bad design.
Valves are small, so the flow numbers are not great.
