Ford 2N exhaust leakage

Got some real bad corrosion around #4 exhaust port. Wondering the best and easiest way to fix this?? Having thoughts of taking the block off the tractor so i can lay it down flat and braze up the corrosion. Has anybody ever tried this?

I used Versa Chem patch on mine, works real well. Do a search in the archives and you will find great instructions on
dealing with this problem.
 
Get the hi-temp metal epoxy. (Not JB Weld) VersaChem's exhaust manifold repair, or ThermoSteel, is said to be good to 2000 degrees. Clean the area real well with brake cleaner, put a little epoxy on it, put some wax paper over it and bolt down the manifold. After it dries take off the manifold and take a die grinder and clean the epoxy that might squish into the port. Look at the manifold, again around # 4. If it?s pitted & burned, it isn?t going to seal. Time to surface it or get a new one. Do not double the gaskets! The gasket has two pieces, left & right (or front & back.....whatever) Use hi-temp Permatex or even Copper coat. Make sure the surface is squeaky clean!

nashranch........as Bruce suggests, there are some hi-temp epoxies out there. I'd take 1/8"-drill and drill some shallow holes to kinda act like rivets to give the epoxie something to hang onto. When you re-bolt yer manifold on, use BRASS nutts. Why brass? 'cuz next time you remove yer manifold fer leaky gasket, the BRASS will STRIP and leave yer studs still screwed into yer block. ........HTH, the stripped Dell
 
I used Thermo steel as Bruce suggested and it worked real well. I used brake cleaner and a white rag until the white rag came up clean
 

I did pick up some Blue Magic Thermo steel at O'Reilly's last nite and dabbed it on around the pitted area, then covered with wax paper and then bolted on the manifold with no gaskets. It looks good to go but i will have to sand or file it down a bit to make it even across block. Tomorrow i will putting all back together and firing up this beast to see how i did
