Agreed. Good block.

Splayed-bolt caps are far prefered for a strong 400SB. "Straight" bolts take material from an already weak area. Splayed bolts tie in to the "V".

As with all modifications like this, quality machine work is paramount in making the engine "live". Measure it closely. If properly done, can easily support 600 HP.
