model a old style header

I looking for some photos of some early banger style exhaust headers. I saw one that was old and had the front pipe starting out stock size going into another larger pipe picking up the other three as it dropped at about a 45 degree angle to the rear. any ideas. I realize the equal length pipes are probably best for performance. I am more interested in the early look for our 4 port Riley B mtr. thanks for any help with this one

 

I had SaltFlatMatt make one just like what you are describing for me. Fit perfect.

Search my posts for pictures. I measured it all up, he made it and it was a straight bolt on. I'm sure he kept the dimensions and everything. If not and you want him to make one, I'm happy to share my drawing.
