Could you post a picture that shows most of the manifold? If it's really a RA III piece, it's a good one - hopefully you have them on both sides.

Ok thanks. I have no clue at this time what hp/torque is for the car. Hoping to have it finished and back on the road by the 20th. Guess ill dyno it as soon as I can. My 428 seems to be just a block at this point its a frankenstien

:agree Those are definitely what you want for a mild to moderate street engine. They run "almost as good" as headers without any of the headaches.
