The TF heads had been CnC ported. I would have liked to see a set of comparable Indy's. But they didn't get a set. Also, as tested the Indy head would have cost at least 600.00 more at a minimum.

I don't think you could do the test with a set of "comparable" Indy heads since the TF heads were CNC ported. The most comparable Indy head would be the basic EZ head. When you get CNC port EZ heads they have MW ports so they couldn't use the same intake. I would like to see my EZ heads in that test because they are ported but still have standard port windows.
