How much bearing damage is too much

Smart move! It is alot of work but it's alot more work and expensive if those bearings make a mess of your Engine.... And the ease of you thinking about those bearings in the motor....

Agreed. And I am only in the engine because I am upgrading the cam, heads, headers, intake and putting the sniper back on. Seems very counter productive to risk that wear when everything else is being done
