Intake manifold studs
 

Removing the CIS system from my 78SC,

4 of the 12 nuts came off with the stud attached.

Is this common?
Should I reuse the studs?
Is it recommended to replace all of the nuts when putting the intake back on the engine?

Thanks in advance,

Use new.. use RED loctite into the block. I put a little antisieze on the outside threads, but many will tell you that this messes up your torque values

Very common with the Exhaust one but 1st time I read about the ones from the Intake.

I use new nuts when I put mine back on.

Many thanks guys.
