Last Friday received the 'new' Cylinder head. Advertised as 'Serviced' , I could choose between 'Brand New' , - 'Reconditioned' and 'Serviced'. Living on an age pension have to be penny wise so went for the cheap option: $850 plus shipping.
It arrived extremely well packed on a small timber skid with very good packaging to protect it.
What struck me first was how dirty it is on the outside - "How hard would it be to give it a friendly cleaning blast ? " - The inside is very clean , looking in the valve gates it is very tidy.

But ... the coolant channels were all full of brown grit .... rust ? Or is it some stuff they used to re-surface the head (very nice and shiny done). Any idea here - see photos.
I blew it out with air and water and some wire and it is all clean now - but I was not all that happy .

Something unfamiliar to me: a spot where it looks welded or so ? See photos. What do I make of that and should I be worried ?

Some expert opinion please .
thanks !
