Hope you have the model number handy I didn't see a quick cross for the cubic inch to horse power numbers. The model number relates to the cubic inches. -- Leon Fisk Grand Rapids MI/Zone 5b Remove no.spam for email |

Correct. I use 14 footpounds with no problems. Thats COLD. After replacing head gaskets, run the engine to operating temperature. Then stop, allow to cool to room temp and torque again. Just takes time to do it right. Test the head bolts tightened at the factory sometimes, the low end engines are often wildly out of spec. |
