Dyno #'s with Trickflow Heads

Trying to advertise heads that are no longer produced... that’s some 3D level business thinking going on here... FYI I did set of EQ heads last year and the guy who flowed them said they were some best small block mopar heads that he flowed, I think they went mid 270s at 500 which is as high as I asked him to go.
Maybe on a build that you aiming for 500 plus HP the trick flows would be a better choice
