Stroke with only Pistons and Crank?

Here is my $0.02. You could you use stock rods, but I would think you would want to have them magnafluxed (they are 50 years old), resized and new bolts. Since the engine is apart, and the crank and pistons are new, I would buy new rods too. I hear what RRR said about trusting the 'prebalanced' thing, but if I am going to trust the parts, I think I will trust the balance also.
