How much torque should be used on the head bolts on a 350 Chevy?
65 ft lbs.
You should measure the diameter of the bolts concerned. The information I have applies to the 250 cc as well as the 100 cc versions of this bike. For the 10 mm cylinder head bolts they torque to 27 to 31 foot-pounds. The 6 mm head bolts torque from 7 to10 foot-pounds. The 8mm cylinder cover bolt should torque from 15 to 20 foot-pounds. Hope this helps. .
Where can you get the head torque on the bolts you also need the the order to of tightening the bolts and the rocker arm torque 89 Chevy Celebrity 2.8?
For all the 2.3, 2.4L QUAD 4 engines, the head bolts are Torque to Yield. The porper torque value is 30ftlbs PLUS a 90 degree turn of the wrench. The bolts must be new every time ( NEVER REUSE OLD BOLTS). The torque values and proper sequence are including in the box the new bolts come with. BUT honestly, the torque value is 65ft lbs like all GM Chevy motors have been for eons.
