I know this has been covered many times, but which heads are better? Trickflow or Livernois heads? I was thinking about buying stage 3 heads from Livernois, but I have heard that they are ported heads for my new edge Mustang Gt and that Trickflow heads are way better? Is this true? When the time comes for me to build my engine, should I just buy a shortblock from Livernois and then buy a set of Trickflow heads??
