Agree that $500 for a factory intake is a giveaway price. Even without a crossover.
If it's a factory 485640 casting intake and still has the 1972-only small opening crossover and shields attached via rivets, it's worth at least $1200-$1500.
That intake manifold alone is worth between $900 and $1200, especially to someone with either an early-1972-built 455HO or a 1973 SD455.
Several of the restoration guides make reference to the 485640 casting being an SD455 engineering 'prototype', even though they never made it onto the production SD455 engines.
An early-1973 SD455 owner might want to use it on his engine to replicate the performance of the prototype SD455 engine design.
The crossover alone is worth $400-$500, probably more if the choke stove is still intact, since it's the only one that works on 1972-up heads.
Good luck!
