Open Block vs. Closed Deck

Why did Honda go with open deck on the 5th gen? Also, why were the journals larger 98+? Any advantages to all this? Just curious.

open cools better but has its disadvantages

larger journals are better for high revs

open deck doesnt cool any better than teh closed eck, its cheaper to manufacture.
and the larger journals transfer heatr better and allow for better lubrication.
