No idea of the part number... I bought them used with a batch of other SBM parts. Edelbrock hasn't made headers in several years... I know they were expensive when new... in the $350-450.00 range.
I would think these would fit an a-body since they really do hug the engine block but the only way to know would be to try 'em. I'll get a couple better pix up this weekend... I'll be home Saturday. Maybe I can post some measurements, too.
