Holley Base Plate missing slot

I cracked the base plate on my Holley 80457 (4160) carb and bought a used one on ebay. The one from ebay is missing transfer slots in the primary bores. (see pictures). Is this going to be a problem.

Everything else about the plates is identical including the part numbers stamped on them.

Yes that will be a problem. It has no chance whatsoever of running right without them.

If the slots are totally absent, then you just discovered why it was on ebay instead of on a car.

Re: Holley Base Plate missing slot

Can you use a very fine cutting wheel to cut them yourself?

Re: Holley Base Plate missing slot

Funny thing is this is a used part and shows evidence of having quite a few miles on it. There is varnish and residue in the bores.

I'm just going to return it I guess.

Re: Holley Base Plate missing slot

Good choice. That just ain't going to work.

I'm trying to think of an application that wouldn't need transfer slots like boats or agricultural applications..... and I can't think of one. I think that's just a actory defect. In any case it's not going to work in a car.
