Darts made power the longest and were the heads with the least amount of work and had the lowest flow. I have read claims of TFS making 50hp over AFR's and this test definitely showed that was not the case. 5 hp was all they saw on the test mule. Seems like TFS is attempting to blindfold the audience with those bogus claims. The magazine also points out the stuff that TFS has over the AFR's doesnt give them all that much help. They go on to mention that a bigger valve will net more. And also that the valve angle plays a role too. And for all that they only were making 5hp more tested on the same cam as everyone else. Something else that stuck out to me was the fact that the TFS heads peaked sooner. These were also a HIGHLY worked set of heads according to the text. Go find you the magazine and read it yourself folks. My take is the AFR's then go Darts. Darts have a lot of room for improvement with the hands of the right porter thats for sure.
