We would always use the original crank/rod bearings in any NEW Subaru supplied block, as the bearings are selective sized to the crank. That is what all the letters and numbers on the front web refer to. Sized bearings are not available to buy, they are first fit only from the factory. BUT they are measured and sized to closer tolerances than any of us after market engine builders can achieve and if it ain't broke,...................
