I had a problem with the rocker posts on my original cast iron heads fitted to my Mustang, two of the actual cast posts had split and the rocker studs were wobbly. Scrapping the heads was not an option and welding looked dodgy.
I found a company in the States that supplies all manor of threaded inserts some of which leave the repair stronger than the parent metal. The FST inserts come in a kit with a cutter and full instructions. I know that your castings are not cracked and you may well do well with a helicoil, but if you want piece of mind these fixings are awesome and actually pulled the swollen rocker posts back into shape due to the dovetail top of the insert.
I shipped them here via USPS very quickly. I would not hesitate to order again even for head bolt holes in a block for which they would be perfect.

Or these without the top hoop and these go smaller in size.
