Ed:  You have considerable experience "brazing" = aluminum=20 such as your runners on your intake manifold; so do you think that=20 method could be successfully used to secure the short = stacks on=20 a PP? 
 
I just received my rods and video so I hope to attempt my=20 own brazing operation this weekend as I fabricate my intake=20 manifold...
