Rover V8 block head bolt thread stipped

So you had a overheat or a head gasket was leaking in the front and your Range Rover P38 went in for it to be repaired, well we've done so many head repairs on these motors I have lost count and the thread damage on the block is common, so common I worked on a plan and it works really well, in effect its like installing studs but to do it when the thread is damaged requires the motor to be removed.
Its always the middle thread to the bottom, I'll be back when I've gone through all the pictures to add on here, so don't lose hope as it can be repaired.
