Any clearance issues with your hood? on your setup? Also, are you running headers or manifolds? (I have heard manifolds can have seating issues with the EQ heads)
No clearance issue's at all with the motor or accessories.
I run headers but the EQ's are direct replacement Magnum heads, which means the factory Magnum manifolds fit like they did on the OEM heads.
I was running these same headers on my 318 in anticipation of the bigger motor and used Remflex gaskets with not one problem in fitment or seal since.
There was a bit of a clearance issue with the headers going around 1.03 torsion bars, but that was resolved with an appropriate reshaping shall we say of the header tube.:D
