So the latest update is, the hole is drilled and helicoiled. It's not exactly centred so interested to see how much free there is in downpipe flange - may need to drill one of them to make the mounting hole a little larger - we'll see.
It took some drilling, but steady away with some cobalt bits - the DT department at work really helped me out.
So now I have a nice fresh hole ready for my replacement stud. But first things first. I need to clean/paint outside (and possibly inside now too), as well as lapping the valves.
Someone from the DT department said to use a dishwasher tablet and some soft brushes to degrease the head before painting. Can anybody verify if this is a) safe to do and b) works well? Also, I was going to use some carb cleaner to clean up the insides (some alloy from the drilling has entered inside - could use a good clean. Is this safe?
Open to suggestions for cleaning and painting - I have some VHT header paint, but would be hard masking the head off, so was thinking to cover it with something using a brush and just going steady.
Any help at all appreciated.
