96 F350 cummins 12 valve exhaust manifold flip or not to?
 

Who has turned thier 12 valve exhaust manifold over when installing a 12 valve in one of these mid 90's model trucks? Where did you get your oil drain tube? is it worth doing so for the clearance of the AC box? ( I know i will have to mod my waste gate actuator so it will clear the AC lines )
