Small block TrickFlow heads part 1

IMO, the pinch is too small upsetting the port from making more power than they do. But if you only open the pinch, generally the port shape needs to be changed...and with the addition of the bowl wing, that complicates things. For the cost of the heads, I don't see people paying for further work to them...however I, like you would love to rework a set and do a dyno session before and after. I think with enough changes, they could be made to make really good power. I just finished a 408 with a small B&M blower, 3psi, street roller cam with 9:1 and made 574HP and 580TQ using the TF heads OOTB.
