hello all, I am knee deep in my 1976 240D 5.5L M117 project and I finally have my parts motor with the SL pan, oil filter housing and manifolds!

my question is, are these 5mm hex bolts going to sheer off on me like almost every single exhaust manifold bolt did?

is there any way to make it so they won't sheer?

I have the new gaskets and my motor is pretty much ready to get dropped in once I get these pans changed.

thanks in advance
