New guy with some manifold Q's
 

Hello, I am new to the forum and am currently starting a 6.0 swap into an 88 Camaro. The question I have is this: Exhaust manifolds? Which will work? I have been told that the truck manifolds flare out too far and will create issues running down pipes. I know the Fbody ones are the preferred option, but has anyone tried GTO manifolds?
