I'm pretty sure if you can have it re weleded it'll hold better than it held new.
Exactly. I'd just go look for someone who does head reworking because that has to be a good quality weld for it to be machined perfectly. A good weld as well as some good prep and you'll be back on the road in no time. Who knows he might even look over the other welds and strengthen those too!
