    The head is secured by 4 long studs, 4 short studs and 2 bolts. Diameter of all will be 10mm. The long studs are about 170mm long, the short ones 130mm and the studs about 120mm. They will need to be high tensile steel as they need to take torque figures of 80lb/ft. Beyond that I can't help much more. Hopefully there is someone else who has access to one to provide thread details and confirm my size guesstimations!

              Yeah no worries, will sort when I get back. Have to ask, what happened to your existing as they're not stretch bolts?

                  No they're not stretch bolts 100% correct.
                  Unless yours are in some way very rusty or damaged they can be used again.
                  Modern engines use stretch bolts, older do not

                          I've just walked in the door. Will sort something tomorrow, message me you address and details please.
                          I have never snapped a head bolt ever so I don't know how they did that.
