Re: Cons of changing headstuds one at a time without removing head? You have nothing to lose by trying it. It will take no time to swap them. If it doesn’t work, then pull the head and put a new gasket in.
Should I use head studs or bolts?
In other words, head studs are better suited for high-performance vehicles with greater power requirements, while head bolts are more practical for personal, everyday automobiles. Therefore, it would be inaccurate to conclude that one type of fastener is categorically superior to the other.
Can you replace head bolts with studs one at a time?
If you want to replace them, pull and replace one or all of them one at time and there are no concerns.

A head bolt should not be reused if the threads are galled or badly damaged. Chasing damaged head bolt threads with a die will clean up the threads but also remove material (metal) and undermine the head bolt’s ability to torque down and hold to specs.
Are ARP head bolts worth it?
The precision and extra strength of ARP means the sockets fit better and the metal on the fastener won’t strip. And ARP mean your mill will live longer and have fewer problems than with stock style bolts. It’s worth it. Better, more consistent clamping on head gaskets, rod bolts, etc.
Why are ARP bolts so good?
ARP’s fasteners are built to withstand serious racing and have higher tensile strengths and can survive higher stresses than most aircraft fasteners will ever see.
Why are ARP head studs so expensive?
ARP stuff is typically more expensive than other brands, but again, that’s because they use more expensive materials, and the manufacturing process, from heat treating to machining, is more involved.
Is it necessary to replace head bolts?
yes, you want to replace them. When head bolts are torqued they are supposed to stretch. They are only made to stretch once. if you reuse them you have a good possibility of one of them snapping which will cause big problems.
