moondoggie, there is a pic of mine in my photo bucket listed below. They were off a 62 engine but a friend of mine said they came off a TRUCK as they had the "bosses" for an oil cooler or something else.
I have also seen some guys use 265 cast iron headers but they're scarce as chicken teeth.
It may also be worth a trip to the salvage yard and just take a walk looking at small block chevies. In your situation I'd think several would work. I've "heard" guys say some off a Chevelle would work but I don't have first hand experience with them. Maybe David can tell you what year he used.
