I'm doing an 836 F3 upgrade and want to confirm the copper washers install on cylinder bolts 5, 6, 7 & 8 under the acorn nuts.
When I disassembled the motor, the copper washers were on bolts 11, 5, 7 & 9.

Correct.  Copper crush washers on 5,6,7,8 only...per the photo below.

Torque chart:



Are those torque settings with consideration of anti-seize? or should you set it 30% lower to 10.15 - 12.67 ft-lbs?

Either way , the factory manual should be for torque it , up assemble the rest , add valvecover, insert in frame , hook everything up... Have it running and out the door same day... With no comebacks..
