Headers for RB in A body

Curious....
Mad Dog Headers....are these made specificly for RB in A Body? B-RB or are these another body style that happen to fit in the A Body B-RB engine?
Ok, got my answer on this....went on the site.
Is there any one with pictures of these installed? 383-440 A body? I would like to know how well these fit, sparkplug wires/ plug access, starter...etc..etc
