Finally got it finished today. It's probably take something like 5hrs total.
Worst bit was the patch in the first photo'. With a straightedge across you could see daylight. The second photo' is how it looks now.
I decided to temporary fit the head just to keep things together, till I get the parts I need. That is when I found another PO's bodge. One of the head bolt holes by the exhaust valve, has been tapped out the 3/8th UNC. Plus the bolt used is slightly longer with a longer shank. Not much I can do about the hole, but the bolt I will cut down to the length of the others and run a die down the shank, to get the same amount of thread.
I get any parts from Meetens, Preston, Lancs. I've found them very good and help full.
