Sneaky trick #2- - - -DO NOT bolt the ends of the exhaust manifold to the cylinder head- - - - -there are dowel pins instead of bolts there for a reason. The exhaust manifold has to be able to expand and contract from the heating and cooling cycles of normal operation. If the ends are bolted down tight the exhaust manifold will crack.
