TR headers.

["Marquis, Gary" <GMARQUIS@csuchico.edu>]

    I am giving thought to building my own headers for my 58 Morgan +4
  (Triumph TR3 powered) and am hoping the wisdom of these groups 
  can help me. The engine has been rebuilt with a big bore kit and a mild
  street cam. What I want to know is:
     Which is best a 4 into 1 configuration or a 2 into 1 - 2 into 1?
     How long should the singles be?
  I don't have the original headers anyway so I have to make/buy something
  and maybe the gain isn't worth the effort anyway.
