The only disadvantage I see with using new good quality studs is the cost of the studs.

I see many disadvantages too using old studs, many of which have been previously discussed. With old studs, you do not know if there are any cracks that are starting to develop, you do not know if they have been over torqued by some previous "mechanic", often there is a necked down area from corrosion that is prone to failure and on and on.

You can definitely feel the difference when torqueing a head, or anything else for that matter when you are using fasteners made from better materials than the materials that were commonly used at the time our cars were built. It costs a lot of money and time to build a good Model A engine and personally, I see no reason to take a chance with old studs or any highly stressed fastener in the engine.

HOWEVER, I am definitely sure that others will have a different opinion and that is fine with me.

We all must do what seems to yield the results we are looking for.
