Sounds like your PO switched the studs to = bolts.

Subject: [VANAGON] Broken = Exhaust Manifold Bolts

In removing my exhaust manifolds = from my 86 Westy Weekender, one bolt broke off in the head.  Does anyone = have any tips on the best way to drill them out?  I was not planning on = removing the head and the position is awkward for clean drilling.
 
Also does anyone know why two = pipes are attached with bolts and two with studs and nuts?
