Step back and re-think what's the goal here.
~1000hp with reasonable manners and durability for a Pro-Streeter.
That being said, a 499" combination may or may not work well. The key is to build the combination for power and reliability. Having thick/strong bores, proper pin height for a strong piston and well placed ring package, good rod/stroke length to control piston speed and side loading etc all factor in.
Next...having a set of proper heads that will be efficient with the engine size under them.
That being said, I would consider a 427 or 434" SBC using a tall deck block, a well prepped set of 18* heads would easily do the trick. Consider a pair of PT70-76mm compressors with S trim wheels and a good intercooler. This is a solid foundation w/ plenty of room to make additional power.
