I would use the same rods out of the C5, they are a lot stronger than the B1 rods. Don't worry about the extra length. Basically what you are going to get by using the crank from a B1 is you are going to increase your stroke a little, meaning that you are going to push a little more displacement and you are going to have a little bit higher compression. You shouldn't have any valve clearance issues as long as you aren't running too hot of cams. So just use the C5 rods and enjoy a little more HP...although I would get the B1 crank balanced so that you don't have to worry about it at high RPM's. The stock B1 crank isn't made to handle the revs of the C5 so by balancing it you won't have to worry about it holding up under the 9K rev load.
