I wanted to start a new thread away from my "Ooops" post detailing my engine swap to cover this as I can't recall any such topic!
My intention is to be able to use this as a dumping ground for information such as head to header flange gaskets, outlet flange gaskets, issues with any particular type of header...
Here are pic's of some original headers and heat shields that I bought years ago from a guy that had a Goose, a Vallelunga, and a couple of Panteras....all red! These were parts that he bought from an unknown car that was being cut up and parted out....
Left side:
It is absolutely amazing how much the builders flattened that front tube!!! It seems like it is only about 1" tall (rectangular shape now!) from the modification. A LONG way from round....
Right side:
Note the hole in the rear tube...I was really paying attention when I bought these(!)...but then the hole may have been covered by old rusty metal and only was knocked out when I started banging them around!
Here are some shots of the RH side installed showing the relation ship of the flange to the rest... Note that these flanges were made "adjustable" fore-aft, by someone...the tubing has been cut off, crudely stretched, notched, and or shrunken...and now slides over the top of the main part of the header assy, held in place with a muffler clamp. Not a terribly good seal from what I see..... I don't know if this feature is original or not...
All that jagged metal you see inside the flange, is old header metal that is not shaped for optimum flow....! Like I said, a pretty crude job. You can also just see the holes in the main tube where the down tubes dump in....no tri-y's here! Not sure what you would call it! Four into one? Hmmmm....
This last shot shows the same cardboard template that I used to determine fit between the two types of aftermarket headers that I have. The flange location is about a half inch further away from the frame, and about 1" higher than these other ones. (I will post pic's of the other ones when I have a chance....they're in my "Ooops" post too...
