I would think RAII heads would be a bargain at $2500! I'm no Pontiac expert but I'm pretty sure they are much rarer than the RAIV (Todd's engine, right?) heads and they seem to be $2500-$3500.
And that's why I'm on your guys side of the fence. There's no reason NHRA shouldn't allow the Edelbrock head as a RA replacement. On the top of my head, I can't think of a more expensive OEM head than the RA heads. Geez, I once bought a restored 1969 RAIV 4-speed Quadrajet for $2800 and flipped it for $3500! Friends thought I was off the deep end spending that kind of money on a speculation. Glad it panned out...
