Yes the outer diameters of the cam bearings are largest at the #1 and the #5 and #'s 2&4 being a little bit smaller OD and #3 is the smallest OD and all the inner diameters are the same .

You should mic each cam bearing and check against cam journals. If they are too tight you could force the cam in and end up burning up a bearing. Not a check everyone does on assembly but if yours is tight worth considering.
Bad news is you have to pull the crank to check past the first bearing with typical home tools.

Mine was tight to go in after new cam bearings with my new cam, I lubed the cam bearings with oil and the lobes with cam lube. But turned ok with no dramas, think I got some cam lube on the bearings as it went in but I put plenty of engine oil on the cam bearings do hopefully will be ok.

Check to see if the new cam bearings are cocked to the side in any way. That could explain your difficulty. The tool that is used to install/remove those bearings is very primitive and leaves a lot of room for human error.

Good idea, mine were installed by the machine shop that put the bottom end on mine together (didn't have the cam at the time). When I looked to see how much room there is to do them I'm glad I left it for them to do.
