Larry,

I used a big torque wrench and set it to 180 ft.-lbs. It never clicked. On the second set of turns I set it to 150 ft.-lbs. and again it never clicked. Went quite smoothly, and yes, I did think I might twist off the heads of the bolts. This is first time the head has been off (the cylinder head height was per the new head specs for height). Other than some carbon crap inside the engine, and a ring of black stuff at the top of each cylinder, the bore of the cylinders was great. All the original honing marks were visible. Jim
