60 lb ft is not correct for the XN1P engine
depending on the serial number of the engine the end result of the torque sequence could be either 37 lb ft or 44 lb ft....
NOT 60lb ft.
The manuals states it could be 50 or 60 N+m not foot pounds. (that translates to what i stated above)

There is a proceedure to install a head gasket and it must be followed to the letter or you WILL over torque the head and either strip out the block threads, break a bolt or warp the head.

If you dont have instructions to follow to do this you're probably not going to get it right and mess up the engine.

In the manual there are 3 separate proceedures for installing and tightening a head and gasket, they are all based on the serial number range of the engine so you must know which engine you have before you begin. You must have the correct gasket also.

You can guess at it if you want but the chances of getting it right are 50/50 at best.

good luck
