Holley 3310-3 question

[HawkX66]

I have a Holley 3310-3 (4160) that was converted with a second metering block a long time ago. The accelerator pump and mixture screws are factory blocked off on the secondary metering block. So now it is a dual feed, single pumper with the block instead of a metering plate. It ran well eight years ago, but since it's been sitting I wanted to throw a gasket kit etc at it before I put it on my motor.
My question is, I bought a Quick Fuel 3-200 for a 3310. Do I just need a set of gaskets for the second metering block or should I have bought the kit for a 4150? I shot a message to Quick Fuel, but I'm sure they're gone until Tuesday.
