Anyone flowbench the trickflow 190 heads yet???

my opinion is that there is very little difference from an out of the box trick flow and solidly worked Eddie regards ET/ mph. I frankly expected to see a notable difference... say maybe pushing 3 tenths type stuff, but i am relatively positive there is nowhere near that kind of difference.

I don’t know why there would be such an expectation from the TF heads.
They aren’t any bigger, and don’t flow any more than the MCH type of CNC job on the RPM heads.

Imo, the biggest benefit to the TF head is what you get for the $$$$, and that they are available with 2” installed height springs.
