Finish drilling holes for tuners

So I'm new to this game...

I ordered a Warmoth neck and the holes drilled for the tuners are not the same size through the headstock vs the headstock veneer.

The holes through the veneer are smaller, forming a lip on the inside of the hole so that I can't fit the tuners through the headstock.

Is this normal for Warmoth necks? I am supposed to finish drilling the headstock veneer holes so my tuners will fit?

I kind of thought everything would be aligned off the bat.

Thanks for any info.
What tuner ream did you order? What type of tuners are you using? If it's drilled for Gotoh/Grover their supposed to be that way. Tuner goes in the larger hole in back, bushing goes in the smaller hole in front.
