[AT] Manifold to head issue

[Gunnells, Bradley R]

I was just taking names off the top of my head as example. Thanks for the reference, I'll look into that.

Since I've not used this tractor much I'm not sure of the overall health and condition of it. I like Steve's idea of brass but I think I'll try the paste options first to make sure there aren't any other issues. I can always come back to it if needed.

Thanks for the suggestions. I appreciate the wealth of knowledge this group has.

I've torn it apart and have a new manifold to put on it but noticed when I ran a file across it that there is a bit of pitting and a slight gap around the port at the end of the head.

But in trying to avoid that time and expense I was wondering if others have found alternate solutions to such a problem. Would something like JB Weld dabbed along the pitted area when the manifold is installed hold up? This is the exhaust port so all pressure is going to be forcing it out so I'm not as concerned about sucking something into the cylinder. Any other remedies folks have tried that have been successful?
