Seeking a solution!

I have a 350 sb with vortex heads, center mount value covers and conventional GM ramhead exhaust manifolds. I am looking for suggestions on how to route plug wires with out manifold interference, over or under. I have looked at several loom setup but have yet to find one that keeps all plug wires free of the manifold. I realize that after market exhaust manifolds may provide the needed clearance.

Any one allready solve this problem.
