If it's a running engine, and you plan on putting the engine in the car without any further cylinder work, fine.

If you intend to register the car using this engine, D4='74, the car should be emissions exempt, and you may be able to obtain Classic Vehicle, or Antique Vehicle tags for it.

The block cannot be overbored any further. Next rebop, it's time for a new block. Old Windsor motors are relatively plentyful, and reasonably priced, even if you have to buy the entire car just for the motor.
