440 big block conversion for a body

I have both headers and b body hp manifolds that go with the package.
Headers are on the motor now with manual steering. The header will not clear power steering.
When I built the car it had power steering and b body hp manifolds. There was only two mods i had to do to get the manifolds to fit. The first one was to cut the sleeve on the steering column back to the firewall. The second one was a was a small dent in the firewall to clear the exhaust flange bolt.
