[Fot] Spitfire Headers

[Norlin Engineering]

Does anyone know of a ready source for Spitfire headers that will stay
tucked up in the frame?  This is for a 1300 and the engine builder says I
should stick with a  tri wye design for the prep level of the motor he's
building.  The headers available from the sources I've found so far are
apparently for street cars since they hang 1 1/2 to 2 inches below the
frame.   
 
Thanks
