Iron head welding

Where does it need welded. Some of this high nickel rod sure works great.
Pushrod hole into inch air port from over porting.
I have thought about what you do on the aluminum heads with the brass tube and JB Weld.

Thanks everyone else. FWIW, FYI, not that it means anything, LMAO…

20 plus years ago I learned and was certified. Took the job, was never given the tools to weld and finally asked…
There reply was the job was canceled.
(Well THANK YOU for telling me, nice to know… ugh!)
Have not touched a stick welder since. Dabbled with my mig.
