New Tool from Bad Cam
Did you make the cut only on one side of the journal? What kind of bit did you use with the die grinder?
Yes cut was only on one side of the cam. You want the journal surface to float into the new bearing with the thick assembly lube.
As the cam starts to get tight with the high spots of the bearings, the assembly lube will start turning gray. Take your time, if the cam starts rotating too tight back it up wipe off the gray lube, put on some more clean lube and go again.
The better of a job you do getting the new bearings in straight and true the easier the cam fitting goes.
I myself used Vaseline to lube the block and outter cam bearings to help them install straight and true, so they are not going in dry taking more force to get them in. That vaseline has a low temp melting point and will cook right out of there on first start when the engine gets up to temp.
Other folks have installed them dry with good luck. I like a little lube in case I have to back up the bearing as it is starting, to get the oil holes to better line up and be on center.
The more of these you do the better you get at it, kind of get a routine down that works.

I just used an 1/8" x 3" diameter cut off wheel with my die grinder to cut the grooves.
