Just a teaser for now...
After a couple of stumbles (bought bad eBay heads and my clumsy work on machining the spring pockets for spring cups and striking water -- ugh!), I finally talked to an old-school machinist who knows these castings inside and out. He diagnosed the heads and said I'd be better off starting with heads that were less bad. He found me a beautiful set of untouched '186 heads. They are now at his machine shop getting new hardened false guides and a light grind of the seats.

Maybe pics in a couple of weeks.
