bending an aluminum header

[rick]

Chris - 
Secure the engine end of the header to a board
then heat the header pipe w/ a propane torch (gently / evenly)
stick a dowel (close to pipe dia) into the pipe to the desired bend
location, 
and bend it slowly once the metal is hot. 
When hot enough it bends easily.

Subject: bending an aluminum header

Since we are on the topic of aluminum, what is the best way to make a 
slight bend in an aluminum header?  I need it to move maybe 1/4" to 3/8" 
at the outlet end of the header. Thanks!
Chris
