All the major brands are good inc Timken, no sweat using them.
In any case be sure to check the shafts where the seal rides for wear, if you can feel a groove it needs a repair sleeve (no big deal). Before I start a job like this I make sure a sleeve is available locally the same day, if they have to get it the next day I buy them and return them if not used.
For the cams its a NATIONAL 99139 and for the front of the crank its a NATIONAL 99145 which is by Timken.
