4100 needle and seat replacement

I have just completed the soaking of my carburetor and on assembly I have noticed the seats that are in my kit are different than the ones I removed. I have a Ford CT-191A kit and the seats do not have holes around the base of the brass seat. Do they perform better than the ones supplied in the new kit by letting in more fuel for performance reasons or will they both be the same.


Thanks
Foley
