Threaded Block and Head Plugs

[Conn47D24]

There are various "pipe thread " plugs in our L-6 flatheads.   

 

Should I use any sealant, pipe dope / tape or the like when installing these fittings ???

IE: 

 

Over Cylinder # 6 , and several oil passages.

 

Also, the water heater valve, block drain cock, and oil fittings.

 

What is the proper install to prevent leaking?

 

Thanks all.

Yes.

 

Any automotive-rated thread sealer.
