I don't think you could cool the heads with the 4 valve design. Wasn't that the short of these heads in their initial introduction and the reason Porsche went to water cooled heads. Heresy!

I don't think valve area/flow is going to be the limiting factor here......HEAT as Beep Beep pointed out will limit this engine. Though it should be a NICE limit.

We wait those charts.....please include AFR's and head temps on the graphs.
