I have a JGS log that clears great, but they're discontinued, so unless you find one used... no help there.
But Treadstone makes a cast manifold (that's not the typical revhard style.) It looks like it'll clear well, as long as you can clock the compressor. $350

Other than that DOC or Xcessive make nice but expensive tubular manifolds.
