360 la heads, I had the 4 end holes in the heads heli-coiled as they were all broken. Now the pass side rear is leaking water should I silicon it along with the gasket? Thanks

studs with the coned washers that is why they are used on the ends of the manifolds from the factory. They will fit and should be used on all exhaust applications. 4 per engine
