headbolt torque
 

Today i have started with putting the heads on the engine.
I did the method of 22ft lbs an 80 degrees for the long bolt,but found out with using the Snap-on tech angle that the actual torque is arround 56/57 ft lbs instead of the 65 ft lbs which is the most common reading older posts.
I did the same method for the rodbolt nuts and i am happy with it,but for the headbolts i'am wondering what to do now.

Just use the torque-angle method and don't look back. :) Normal torquing includes friction that affects the torque reading. That is why the torque-angle method exists (to eliminate torque errors caused by friction).
