There was annoying rapp when accelerating , I thought that it was because of plugged heat risers and unplugged them , same rapp. I made small (app 1") equalizer tube and app was gone and nice flathead sound is there all the time. Maybe I was just lucky...

You are correct, that is part of what the equalizer tube does, it cancels out some frequencies. A traditional Hot Rod engine would not have had one, so the sound is going to be different. But if you like that way it sounds with it installed then there you go.
