So long story short im getting metal in my oil and im gonna pull the pan and check the rod bearings and i rather have the stuff when i pull it then have to pull it apart again later, so i was looking and the bearings were said undersided and im not sure which i need any help will be greatly appreciated thanks

 

dont buy anything untill you open and check everything , I learnd the hard way

you might need .010 under or 0.020 under , you might even need a new crankshaft

and you most change cam bearings if they are slightly damaged , the cam and the cam will damage the new bearings unless pulished

agine dont nuy anything untill you pop that motor.
it might be a good time to upgrade to a 6.0

 

This is true, you will want to check clearances before installing anything. Not checking, and just throwing another set in there could possible result and worse damage.
