Bearings

Alright, I need experienced people to reply only. I dont want any opinions with out reasoning.
I'm going to be rebuilding a LA 360 motor in a 70 challenger soon and I want to know the best performance bearing on the market and WHY.
Right now the motor has edelbrock aluminum heads, intake and 600cfm carb, roller rockers, big bump stick and stock bottom end.
Plan is to put KB pistons in it to up the cr a bit and get some more hp. I want to work over the heads a little also.
So I'm wanting to know what the best performance bearings are on the market today. Also, if you know what rings i should use. (Cast or moly)
Any other tips/tricks would be helpful to help make some more power too. I'm not a novice, so don't talk to me like i am.

Thanks!
