Thanks guys for the answers to my question.
I got one "fit a header - a Monza"
one "fit a header - anything but a Monza"
one "don't bother welding it"
one "welded carefully, it'll outlast the car"
Only thing I didn't hear was "buy a cast iron original style" Well,
that's what I did today. The local shop just happpened to have one
there, $C100. Said they are very rare. Also said a new header would be
about $C275. So, perhaps I got lucky.
Thanks for the answers.
