cleaning up the slant six head

I was able to find that paper fairly easily and here is a link to that in case anyone is interested. http://pubs.acs.org/doi/pdf/10.1021/ie50174a010

Given the condition I exposed the head too Id say this is a plausible answer to the issue I had, Id guess it would take alot more time and money to reach a definitive/ unarguable answer which Im not in a position to support.

This was my final attempt at explaining what happened with this cylinder head, I need to move onto my next steps with my new head and all this has taken too much time already.

I will add that I did re-soak parts in that original batch of vinegar and although I did not let anything sit for the week duration I could see that because of time and use the vinegar had lost much of its bite, not nearly as aggressive as it was straight out of the bottle.
