My service book says ring end gap is between .002-.014 with .010 being nominal.A previous post lists the cylinder head torque at 70 ft/lbs.Be careful if you are re-using old bolts.They may be stretched and a little weaker than new bolts.

In that line a 3" bore would use between .009" to .012" ring end gap. Tony 1938 1/2 ton Hope to drive it before I retire
