<p class="MsoNormal">All replies say that it is fine to re-use the studs and nuts, provided the threads of both are in good shape and there is no corrosion etc. on the studs. The key is to achieve proper clamping, which requires the threads to be in good condition
so as not to waste torque overcoming thread friction.</p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">After a good cleaning, I chased the threads on both nut and stud, noting no removal of metal from any of these pieces. Nuts spin freely down to the end of the stud thread. I’ll be re-using them, just as soon as I can get one exhaust valve
(out of stock where I’ve looked but expected soon, seems to be a common feature of supply chains these days.).</p>

<p class="MsoNormal">I respect your collective advice and experience. The 4A’s head is at the machinist for a cleanup (head gasket failure). Would any of you re-use the head studs, or would you replace them? They are likely original, and even if not, have been
in place for at least 25 years. I have my thoughts on this, but am interested in yours.<o:p></o:p></p>
