Will do. Thanks for the heads up.
I am not 100% sure what the thread is for the head bolts, so if you do go down the lifting eye route, get the correct thread type.
You can get lifting eyes without the shank, you may be able to use one of the short head bolts and a female lifting eye....just remember which ever you use, place a large washer under the lifting eye to protect the head surface.
I think they are called eye nuts.....get one with a thread size larger than the head bolt diameter - or drill out the thread in the eye (as a LEEA trained examiner - I didn't tell you that though!!)

If you have a shufti here,
It reckons they be M10 &M12 not sure of the thread pitch tho.
Does your die kit not include a thread gauge?

years ago i had to fit a complete set of helicoils after someone tried cleaning his threads with a std pitch tapNever thought of that!I'm beginning to think you have done this before
Sadly not, neilly.
I've tried one of the smaller diameter bolts and it appears to be 10mm x 1.5mm. Went on easily by hand in the open position (not in wrench) did clean the thread a bit though.
My 12mm die is x 1.75mm and it doesn't fit the larger bolts.
Good idea. I'll go have a count of the threads over a set measurement.
Did they realise in time or just couldn't torque the head down?

a couple of the bolts stripped their threads on the last 60 degrees
Right, I've had two bolts up against a measure. I'm cracking on a bit, my eyes are dim and my knees are knackered, so I used a magnifying glass
17 threads over 25mm, so they must be 1.5 pitch.(17 x 1.5= 25.5mm) Why does my tap and die set have a 1.75mm pitch die, typical
17 threads over 25mm, so they must be 1.5 pitch.(17 x 1.5= 25.5mm) Why does my tap and die set have a 1.75mm pitch die, typical
At that point I bet he thought, 'Oh, sh@t'

its 1.75 in your set as thats std for 12mm bolt 1.5 for m10 and 1.25 for m8Right, I've had two bolts up against a measure. I'm cracking on a bit, my eyes are dim and my knees are knackered, so I used a magnifying glass

Not lined up well for the camera, but 10mm and 12mm
That's why these aren't standard then. They're M12x1.5
