Hi All,
You can see the rust/crap on the port side of the guides, this would have ruined the head if you tried to drive the guides up from the ports *eek*

In the first photo of the plug threads they seem well corroded, ?? An insert may be advisable

To remove the rust, if you cannot get the head blasted, look up citric acid rust removal or electrolysis

Yes I have access to blasting, but don't think I can clean up the ports without messing up the seats.
I have used electrolysis before, so I might try that.
I'll leave it a couple of days to ponder.
Cheers
