Competition Can head bolt studs be re-used??

[jtisdale]

A friend of mine has a 5. 9 12 valve (out of a truck) converted to alcohol in his pulling tractor. He had problems with head bolts breaking, so he had it studded. I have always been told (with any engine) its a good idea to replace the head bolts when you pull the head. Does the same apply to studs?

You can reuse both.

Just make sure that the bolts are in spec. and have not stretched too much.



The studs, I would call the manufacturer and ask their opinion.

I never reuse head bolts. Head studs can be reused. They dont stretch like head bolts.

This is good info, I'd say e-use the studs also as your just clamping down with them not turning the threads.

I have reused studs many times on engines and equipment. I hope I don't have to find out on my dodge. My truck does not make enough hp to warrant studs. I have cleaned many a stud for turbine shells. lol Jim

As long as they have not been tightened to yield, and measuring them shows they have not stretched, they are good to use again.

You can re-use head bolts as long as they are with in spec's. Head studs are the same way.
