I have a set of nice partially fabricated headers for a BBC engine in a chevy vega,
but it doesnt have a single flange at the head side.the previous cars owner bent some of the tubes for chassis fitment reasons,
but now its out of whack on the head side.do any of you guys have the bolt locations in a print diagram or a printable file?
I If I had that info I could easily tap them into a piece of aluminum and try to straighten the tubes out.
I dont have a spare head lying around.

you could just order a set of header gaskets for a BBC, matcching the heads you intend to use,
that would give you a decent pattern, and something you could use to have some guy use it as a pattern.
or buy a BBC header flange made from steel or stainless steel you could use to complete the header fabrication
