Edelbrock fit issues

Having a real hard time getting a Super Victor 2815 to fit on a set of Edelbrock heads. Finally clearance enough to get the valve covers on ,with doubled up gaskets....but can't get the bolts in on the #3 and #6 intake holes in the head. Trying studs on those 2 but was considering putting a slot on 1 side so I can have stud on each side. Any guidance would be appreciated.
