ch740 head torque

I am replacing the head gaskets on my Kohler ch740 and the head bolt torque says 300 in lbs or 25 ft lbs on the flange nut and 370 in lbs or 30.8 ft lbs on the head bolts is this correct? That seems really high. Any help would be appreciated.

Yep...300 in lbs for studs with washers and nuts....370 in.lbs for regular headbolts..
If you overtorque them...you can strip the threads outta the block...
I use an inch pound torque wrench for that reason...

Ya beat me to the draw again...Fish...

Part number faces OUT towards you. If you have the head gaskets that end in part # 37 throw them out, they will fail again. You want the head gaskets that end in 04. Did you check to make sure your heads were flat??
