Loctite Any Internals?

I am chasing threads along with getting the block ready to paint. I will be building my 351W within the next week (I hope). I was wondering if it is a common practice to loctite any of the fasteners? The ones in particular I was curious about would be the cam thrust plate bolts and the oil pick up tube.

Any and all advice welcome!

Thank you in advance:

I haven't loctited any of the internal fasteners. I think most of those are supposed to be torqued to spec with oil on the threads to lubricate them, and I'm not sure you would want to use that much loctite.

As for advice - get it CLEAN! Get every last bit of debris out. Blow out the passages using brake cleaner and then blow them out with air.

I use red on all connecting rod bolts and main bolts.

... and any oil gallery plugs, like the ones on the back face of a 460 block.

I'm not sure I would use red.
I sure wouldn't want to take a torch to a rod or main cap to get it off.
And with the block as a heat sink I don't think there is any other way you're going to get those bolts above 450°F

If screw in yes, if press in I use RTV.

Warning: Thread Creep Ahead... I was lucky enough to still have my grandfather around, a John Deere heavy equipment mechanic, about 20 years ago when I was trying to undo a previous owner's very thorough work on a head. He showed me that beeswax melted around the head of a bolt will seep in via capillary action and work loose a thread secured with red Loctite That man forgot more than I'll ever know. I still miss him.

LOL! I like that - thread creep.

And, that is an interesting tip. I'll bet you miss him.

Press in oil gallery plugs?

Do they really hold in front of 70 or more psi of oil pressure?

Lots of engines have press in plugs. Yes they hold. There are millions and millions of them on the road.
