Hrm... I never thought cast iron was that bad to weld that "nobody" in Reno can do it.
Also, I doubt that Rusty's plugging headers that see 1750 deg F temps and pressures like our turbo headers see. On a N/A motor, a tiny leak in the headers would probably go unnoticed... on our cars they become "rape whistles" as you so eloquently put it.
But hell, give it a shot. Worst case scenario is you've just got a slightly bigger hole to patch up later.
