Torque Wrench
I have to change a cylinder head gasket. Is there any one torque wrench/size that works better than others? Will a 3/8" torque wrench tighten all of the head bolts without any adapters/homemeade extensions?
Thanks
Thanks

Torque wrench
I find it easiest to use an obsruction wrench. They have a 9/16 box on one side and 5/8 on the other. Put a allen socket on the torque wrench that fits in one end of the obstruction wrench. Keep the torque wrench at 90 degrees to each bolt being tightened. You can get to every bolt with this set up. I use a 1/2 torque wrench.

The C shaped wrench is also called an obstruction wrench. I have been told, if the torque wrench is used at a 90 degree angle to the two boxed ends, you get the correct torque. If it were a little more or less torque, you still have even torque on all bolts. I too used the two huffs and a grunt method of tightening before I found this set up reaches everything. The obtruction wrench has 5/8 one side and 9/16 on the other. providing you have both a 9/16 and 5/8 socket allen, you can do both the head and base nuts with this.
