I torqued the 3/8” head bolts to 45 foot-lbs. Might be too much but I never got a nervous feeling like one is gonna break. I think they’re Grade 8 and I used the original IH bolts which might be stronger than Grade 8. I got to about 28 foot-lbs on the 5/16” bottom plate bolts after gradually ramping up the torque and stopped there. I think the 35 foot-lbs has to be a mistake and it felt like I better stop.

Following advise from previous threads on this topic, I used Indianhead gasket shellac on the bottom plate gasket only. Nothing on the other gaskets. I did not use sealer on any threads. My understanding is it acts as a lube and you have to adjust the torque down if you use it. I’ve broken bolts before using the silvery colored stuff in the gray can (drawing a blank on the name right now). With this being a protected unit under the hood, I just ran a clean out die over the bolt threads. There was no rust on the head bolt threads. They looked real clean.

You could use a thin film of sealer on the bottom cover gasket, it might help to keep it from seeping over time.
Permatex Aviation Form A Gasket is good for that, it is a non hardening liquid. They sell it at NAPA here in the west. If you buy one, stir it well before using, it can settle in the bottom of the can sitting.

It is used on engine head bolt threads to seal them also. Below is a pic. :)
