		Weld the intake manifold closed.
  Some folk just use a blocked-off intake manifold gasket, but they'll just burn-up and blow themselves apart.
  Actually, it doesn't matter which type of intake manufold gasket you use (blocked off or normal) if the manifold is welded shut - it'll seal either way.
  If it's an iron intake, I'd mill out a small rectangular recess about .065" deep and stick a piece of 1/16" steel into the recess.  This'll hold up fine, even if the engine backfires.  Too thin a steel plate can blow-out during a backfire.
