I know some people always replace them, I have never replaced them and
never had a problem with head gaskets or heads--the includes Sprite/Midget,

Somebody, maybe Randall, said run a good nut up and down the thread, if
stretched it will bind.

Thanks to all of you who replied, either on the list or privately. I apprec=
iate your advice.

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 stu=
ds. 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.

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 en=
d of the stud thread. I=92ll be re-using them, just as soon as I can get on=
e exhaust valve (out of stock where I=92ve looked but expected soon, seems =
to be a common feature of supply chains these days.).

Best regards,

Cliff

Subject: would any of you re-use head studs?

I respect your collective advice and experience. The 4A=92s 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 i=
f not, have been in place for at least 25 years. I have my thoughts on this=
, but am interested in yours.

Thanks,

Cliff
