Allez Sport headset bearings

I had a creaking sound when turning even the slightest bit and after inspecting the headset bearings, it turned out one of them (the bottom I think) needed replacing. I cleaned it out and loaded it with grease until I got new bearings and reinstalled it fine.
I bought a pair of these http://www.chainreactioncycles.com/cane ... -prod11266 which I had come to the conclusion were the right bearings for the bike (Specialized Allez Sport 2013). However, I've just tried fitting them today and they don't fit as snugly into the headtube as the olds ones did. Comparing them side by side, the tapered part of the bearing is deeper on the old ones than these new Cane Creek ones. I carried on thinking that it was just a small difference but when it was all back on there is a small gap at both the bottom and top of the headtube and the bearings are visible through the gap.
Have I bought the wrong bearings or should it be like this? Would buying a Cane Creek headset to replace the standard headset solve the problem with the gap? And if not, which bearings are suitable for the bike?
Also, while I have a thread going: I accidentally sheared the head off the centring screw on the Sora brake block. I've taken the one out of the other brake block to have a look at it and it has a 3mm head with 10mm thread length and a domed end. However, I'm struggling to find one online, my searches return grub screws which don't have a wider head than the thread (would these suffice) or screws with flat ends.

I replaced the headset bearings on my 2011 Allez Sport. There is a detailed thread on here that I followed. I had to knock out the plastic cups inside the frame. It sounds like yours is different though.0

I've tried searching but couldn't find much info. What are the 'plastic cups?' I had the top cap, then the stem, a couple of spacers, the tapered ring which sat on the headtube then the bearing sat inside the head tube (flat side up), then at the bottom of the headtube the bearing sat flat side down inside the headtube and a rubber gasket thing and then it was just the fork. Was yours different to that?0 -
Find your frame on ones of these and it will tell you what size bearings you need:

Ok, it says both the top and bottom ones are "M ACB 418H8FM 41.8*8*45D Eco."
Would this be the correct bearing? http://www.ebay.co.uk/itm/30-15x41-8x6- ... 1c418f0e910 -
No if it's "M ACB 418H8FM 41.8*8*45D Eco the bearing height is 8m the one you posted the link to is only 6.5mm high. Looks like you would need 1 1/8, 41.8, 8mm size instead - e.g.
http://www.ebay.co.uk/itm/Sealed-cartri ... 4897.l4275
or scroll down a bit here

plenty other bearing suppliers out there and you nearest Spesh dealer will probably give you a set if you ask nicely (mine did!).0 -

Thanks for the help, I thought I was looking at an 8mm one, ebay is full of bearings from China I must have linked to the wrong one by mistake.0 -
No probs easy done - as long as its a 1 1/8 steerer (which it should be) then that's the right bearing. Its easy enough to check the fit anyway.0

The bearings look fine. I did the same job on my 2012 allez and the bottom bearing had fallen apart. I didn't realise that the bottom of the bearing was still attached to the forks, and that gave me the same gap you describe. Had to chisel it off with hammer and screwdriver. Are you sure you have all the old bearing off the fork?0
