I have a 67.5 1600 also, actually, 2 of them. My first one had a factory
manifold on it, but it really leaked, so I put on a header from Ralley. It
lasted about 40K miles before it broke. My second car came with one. I
don't know how long it has been on.
My understanding is that the factory manifold was quite good and that you
couldn't make much of an improvement by putting on a header. Manifolds
are also very hard to find and cost big bucks.
I am planning on converting my 1600 to a stroker, so when I bought a new
exhaust system I put in a factory 2L system, so it is ready to go.
If you decide to buy a header have it ceramic coated before you put it on.
This will keep the metal from rusting out as fast. It also keeps a great
look much longer. Oh, another thing. The factory exhaust system that I
bought was painted black when I bought it, but the first time I fired it up
most of it blistered off! Strip they paint off and put on high temperature
paint while it is out of the car.
Peace,
Pat
