Head Bolts

Postby wagonmaster » Tue Jan 21, 2020 10:28 am

With the head bolts all going into the water jacket, what should I be coating the threads with ? Will be getting new head bolts. Also , I see one place selling stainless head bolts. Don't know anything about metallurgy . Would these be strong enough, and what about the reaction of dissimilar metals?

I use brush-on teflon; got it at Napa. I have used teflon tape, too. I have never used the stainless steel bolts. I usually get replacements from my local dealer. There are two different lengths, 9 short and 6 long.

I have some of the sealer used for natural gas pipes but have never heard of anybody using it for head bolts. Think it would be ok? Kind of sticky though. Concerned that might effect torque values.

Quoted torque specs are either clean and dry threads or clean and lubricated threads, not a lot of difference. I don't remember off the top of my head which is called out for the Cub head bolts. Either way, a sticky sealer might throw the measurement off. I prefer to use something like the Teflon sealer, or anti-seize that are lubricants.

The number cubs and the farmall/ IH cubs share the same c60 engine. Anything engine replated has a lot of coverage in the farmallcub section.

From my drag race engine building days I still coat the bolt threads in water cooled engines with #2 permatex. This way the coolant can’t creep up the threads. I also spray the headgasket with hi tac permatex sealant spray.
I'm technically misunderstood at times i guess its been this way my whole life so why should it change now.
