Head flow and power differences question / discussion

I’m still not sold on TrickFlow heads. After seeing two good ports, (298-300) one bad port (280) and one super turbulent port I’m not sold on them. I’ve really only seen one good running set and that belongs to a member here.

We've made just under 580HP with them, using a hyd. roller cam! But they need work, they were not ootb heads at all. Compression was 10.7:1.
