best use new ones on that.
because ?
all the more reason to reuse the old ones - unless they've been in and out a good few times

There is some jobs where only new bolts will do.for me this one of them.
YES you can reem up the old bolts and YES it may work but as said its best to use new for a good longterm result.

what are you doing to the damn thing.. I think if I'd had my heads off 4 times in a week I'd be considering junking the motor..
how do you "reem up old bolts" ?

I don't remember all of my brief studies in metallurgy but I do remember there being two phases of deformation in metal: Plastic and Elastic. If I recall correctly the elastic you get back when you release the strain and the plastic you don't.
If you try to reuse a bolt that has been designed to do its job availing of both forms of deformation (i.e a stretch bolt) I certainly would not reuse it for the same job. Its probably fine for hanging a gate but I wouldn't bolt down a head with it, absolutely not in a engine known for head gasket problems.
