Are Speedmaster Heads Good? I've Heard a Lot of Bad Press on Edelbrock 340 Heads Lately

I’ve got a set from ProMaxx. They are cast overseas but all the machining is done here in the states. Nice casting and good machining. They have an as cast and a larger CNC’d port available. Not quite as much flow as the TrickFlow but better than the speed master versions or Edelbrock. Priced in the middle, for another option.
