If you click on it they have some suggestions on head installation for the flathead

I used pipe dope (pipe thread sealant) when I assembled my engine. So far so good.

The torque for a bolt is generally about 70% of its dry shear strength, but you must be aware that any lubricant applied to those threads (pipe sealant, Loc-Tite, etc.) will allow them to reach that 70% mark at a lower reading on your tourque wrench. I think those lubricants are viable and I use them myself but be aware that they will change the settings.

Last time I re-installed my head was after I'd installed my OD tranny and I had several headbolts with threads in their slightly enlongated heads, and it didn't take me long to figure out that these bolts were meant to hold the bracket that carries the OT ignition\selonoid switch. If you have bolts like those I mentioned (I think there are three of them but I'm not going to shovel two feet of snow off the hood to count noses) and plan on installing one of those brackets you might want to consider placement of the bolts accordingly.
