as to how to check intake fitment, hughes has a tech article on how to check the intake that may be a better way than how you have checked yours.
the link is over on the Q&A board under an intake leak thread. hughes lists it under "intake manifold sealing".
i don't know how to jump over there while typing this, and copy the link. sorry.
also, i'm not trying to bash the way you checked, or insult you in any way, rather just adding another way to check your intake fitment.
