If the bearing material isn't "peeled" from the backing, just "shined" a little, they should be fine.
New bearings should NOT make an engine "tight". in fact, we use what we call "the two finger test" for the mains. That is, once the mains are installed, lubed and torqued, you should be able to grab the snout of the crank and turn it with two fingers. Same with the rod bearings, but the friction from the pistons and rings WILL make it much tougher to "turn".
Where are you buying those bearings??? That's HIGH! About double what we sell them for, anyway. Federal Mogul part no. 4123MA-xxx. Same as the 153. They are NOT "marine specific".
