Magnum Exhaust Manifolds in an A Body

Hi guys, well I was planning on the magnum manifolds for my '74 Scamp project that I intend to have a low stance but reading the 4 threads I am headed back to stock manifolds since I'm not running over 300 hp.... but what I don't see is the specific problem with the manifolds just "grind the heck out of the manifold/steering box or find a welder who can weld a manifold"
My motor is in pieces and I am looking at the engine bay wondering if the power steering box can be lowered just a bit and the motor raised just a bit but then I still don't know if the clearance problem is due to height or width. Also, I know this is strange since I haven't looked at the steering column but what if it was moved to the right 1/8' also... yes that would be some work on the firewall but darn it.... I want it all-- a great sounding low daily driver.
What are your thoughts ??
