Frank,
I agree completely with Brion.
Far to many spongey areas and myriad cracks waiting to fly merrily apart despite much polishing - this, I think, is where the bleeding rust was comiing from.
The other horror is my favourite thing about rod heads, the evidence of worn out dies used beyond thier replacement date, Viz the uneven heads, the protruding flashes on the flanks of the heads where the mating faces have chipped and the machining marks on one side of some heads whre the loft probably made thier own replacement die after some clumsy unsupervised apprentice broke one half of the die set.
I know all about breaking dies in Navtec or other heading presses, I was that cocky and arrogant aprentice for about twenty minutes back in the seventies!
A short sharp lesson in my actual worth as opposed to my percieved worth with a side excursion into the market price and availability of dash 60 Navtec dies focussed my attention and helped an awful lot in assisting me in ongoing career decisions.
Talk to the loft doing the replacements, (do not be seduced by the cheapest quote , although it is quite possible that the best IS the cheapest, usually because they are the quickest and most professional about the whole deal, and do not mind investing in new sets of dies occasionally) mention that you expect properly formed heads, they will harrumph a bit and tell you that the ALWAYS form the heads properly, I hope they do, if they dont, squeal like a hog and demand replacements..
Having said that, these deformed and incomplete heads have not fallen off for a scrillion years.. .so what do I know.
Am I right in thinking you are going to replace the complete set, tangs, rod and turnbuckles?
If so, how about looking at the chainplates as well...Oh no! Pandoras box!
Good luck.
