I had an Izuzu 2.6L that overheated (not like that was common), and there
was a 6-month backorder time from Izuzu on new castings.  My head was warped
0.009", service was something like 0.006".  I had it machined flat (I needed
wheels ASAP), and the cam ended up breaking 10,000 miles later.   Learned a
lesson about OHC engines from that, and I can proudly say that I haven't
broken a cam since:)
