Frank,
I recommend you find another machinist. You needn't care about the
condition of the pistons, since you're not going to re-use them anyway. You
should be able to take the motor to your rebuilder and expect he'll solve
the frozen engine problem.
There's a long block on eBay which the seller calims has been rebuilt. If
you can satisfy yourself that he is offering a solid product, it will be a
lot less expensive than starting from scratch with your seized motor.
