Yanmar YSE8 renovation Part 5 Cylinderhead to cylinder

Check with your supplier of head gasket if you should or not should use jointing compound. If you use a Yanmar gasket you should not use compound. I use a Sunity and should use. Hylomar I used. The head nuts shall be tighten in steps diagonally, not to the final value at once. Tightening torque differs between the service manual for YSE8 and YSM8. More than I have used the higher YSM8 value by misstake. Not clear if the higher applies to both or not
