I removed the head shields for some work I'm doing on my 1.9L.  Each is
bolted at one corner with an exhaust header bolt; the passenger side shield
is bolted at the front of the engine and the driver's side shield at the
rear of the engine.  I didn't notice when I was removing the bolts but the
only bolts I have left that should go on the headers are two different
lengths, one about 30 mm and the other about 25 mm.  does anyone know which
bolt goes on which header?
