Yes you never reuse headbolts
yes
not recommended
No because the ports on a tbi head are different than the ports on a vortec head, vortec heads need a vortec intake however you can switch a carburated engine to a tbi engine because the heads are the same
I would not recommend it. The bolts are stretched during the torque procedure.

You can, but I would advise against it. The old bolts have streatched and you should install new head bolts.
The head bolts will not have the same clamping capabilities, since they were stretched on the first installation. You may blow a head gasket due to the bolts losing torque.
Yes, if they are not damaged in any way.
The big difference with a vortec vs normal gm motors is vortec has different head design and the intake manifold have bigger runners. In 1995 vortec heads still used T.B.I injection with the top end of the engine being vortec head and intake mainfold.
