1965 4-barrel intake

Hi, does anyone here have a 1964 273 4 barrel intake? I am just doing a minor upgrade to the existing 273 in my Plum Crazy 64 GT. I don't want to get into changing the heads on my motor. If I wanted to get into that much work, I would just put the motor that Moper built for me in it. I want to keep that motor in my Pearl White 64 GT. If nobody has one, can someone tell me if I can just use a Performer Intake or do I need to drill different angle holes in the manifold?
