All bolts are M10x1.5. There are 13 that are 61mm long. There is one on drivers side that is 36mm long. Then the 2 long ones, 101mm, 1 per side. Then the 4 studs. They are M10x1.5 at the cylinder head and M10x1.25 at the nut. 75mm long.

Thanks ikeG!

Would you happen to know what the length of the uppipe bolts are? I am guessing they are M10x1.5 maybe 20 or 25mm?

Up pipe bolts' threaded length is 27mm but they have a substantial dog point.
