My Hemi block was machined for SS racing, short deck (10.40") and 2.500" cam bores for the BB Ford cam journals (2.125"). It has the standard Babbitt bearing on #5, the rest are the BBF.

I would think you would only want .001"-.002" press fit. Not really sure as heads are holding up my build (thanks MCH).
