Advice on using Loctite on the allen bolts on my Mikuni 2 into 1 inlet manifold

The four Allen bolts do have lock washers but I do worry about the 2 inside Allen bolts coming loose and being sucked into the engine...

I am thinking to use Loctite 246 which is medium strength and operates up to 450 degrees before it lets go

Does anyone have any thoughts on the Loctite and what torque I should use to tighten the bolts?

Thanks
Dennis
