1) Taller cap, more material at the bridge, more strength and less deflection
2) No factory Pontiac block has the cap register design (same as BB Chebby).
Your "register" is actually just a hollow dowel and has less strength vs a solid dowel.
Very easy to mod a cap and block for a 5/16" (.312) tall solid dowel vs machine for a 'ring" that effectively takes away some of the clamp load surface area on the block and the main cap. So the design is flawed.
3) I agree that an extended skirt is stronger. Even a 3/16" extended skirt (like the one added to the All Pontiac Block). In a perfect world you would have a Hemi deep skirt or Ford Deep Skirt design and a cross bolted 6 or 4 bolt attachment design. but most are in love with the Pontiac/chebby design as it is traditional Pontiac/GM design.

ps I have never seen a 5/16" dowel (.312) as stock on any pontiac block or any print showing that larger diameter dowel pin.
