Do you personally remove them? if yes, how? Will they drop out in the oven?
When the engine heats up when ran they will eventually fall out and cause big trouble. It is easy to break the block and/or side cover trying to get them out if not careful. Yes, heating the block helps. A very small puller can be used. I have seen bread used to remove them. Yes, bread. Bread pushed into the center hole until full and then a dowel the size of the hole beat into the bearing. Repack and redo. repack and redo. It will eventually drive the bearing out. Been told you could use thick grease also. I have also seen them staked in. Take a sharp punch and dimple the aluminum quite hard around the bearing thus causing them to be tight enough to stay in. the aluminum behind the bearings is quit thin. If you do bust the block behind the bearing you can use a freeze plug of the right diameter to fill the hole.
Probably the best idea^.go to habor freight an buy a bearing removing kit 30 bucks that how I got mine out
Warm up the block and sidecover in an oven (toaster oven works fine) and they all but drop out on their own. Light tap and they fall out -- watch, they'll be hot.

Aluminum melt temp is 1200 degrees, 3-350 wion't hurt it.
Not really, the block would never get that hot when the motor is in use. If you block is anywhere that temp in the bearing pocket area the bearing falling out is the least of your problems.
