A fully skirted, deep block design with large cross bolts is a superior design for very high HP applications, little argument there. A bolt-on girdle band-aid apparatus of some type would also help some depending on specific design and how it was married to the block. A billet block with smaller mains and a skirted block would be better suited to the Boss Bird application. It would not be "Pontiac" enough to the guys who own it though. So far, at least, cap walk and fretting have been tolerable. Best possible race block? No, that would require a billet block that was not a "Pontiac" IMO. The Boss Bird cast Aluminum block is a stock dimension, stock deck height, 3" main traditional "Pontiac" block. Any production Pontiac head will bolt on, it uses a stock dimension lifter valley cover, timing cover, oil pan and valve covers. Everyone has their own idea of what a Pontiac needs to be, and it varies allot depending on who owns and races the car. Honestly, at an open event, more people think our engine is some type of small block or big block Chevy than a Pontiac. They generally figure out the narrow cylinder heads and plug wires not going through the middle of them must not be a hemi.
