Are these small oil gally plugs in ok?

I leave them out. They’re pretty much worthless.

Do you mind me asking a question? Here goes.

If the cam retaining plate covers both holes, why do the books all say to stake them in? I don’t get it. Like I said, I don’t use them. They are redundant.

But why stake them??? They can’t get out. They only way out is through that plate and no way can you turn them either.

That makes no sense to me.

I don't think a 340 ever had them, none of the old motors that I can remember had them and I have disassembled many SB mopars, mostly 73 and older.
