First picture.
I think you will strike water going that high with the bridgeport, stockport seems fine, I'll guess you've used a template for it.
Second Picture.
I don't know what center iron that is, just make sure there's enough meat when going that deep with the original port.

Keep the centre plate port outlet small if this is a street driven car. Just focus on the transition points from runner to outlet. The bridgeport cut on the centre plate can be 1-1.25" in length. Secondary bridgeport 1.5 to 1.75" length. Bridgeport width start with 7/64" and clean up. Don't port up on the port outlet; just port down and focus on the transitioning like on the primary. No reason whatsoever to have ports the size of melons, especially when considering a bridgeport. The more iron material leftover the stronger and better the bridge itself will be.

Brian, how do you manage to get your portrunners so smooth, mine allways looks rough ?
A little trust and some pixie dust goes a long way.
