Yup. That would do it. Those front holes are not threaded from factory. The plugs are pressed in then staked in place.

More specifically. Threaded rear galley plugs are removed, front ones driven forward & out with a long rod, stake marks & distortion removed with a tapered reamer, and new front plugs are staked in place again. High pressure pump will NOT blow them out if proper procedures are followed. All this is SBC rebuild 101.

To be honest the work I see in that image looks shoddy as hell.

As for the high nickle thing. Hope somebody did not convince you to pay extra for a "010" cast block.
