You need to take your rods to a machine shop and have them measure the inside diameter of the big end with the bolts torqued. This is a VERY VERY critical dimension and needs to be checked with a very accurate bore gauge such as the one on a Sunnen rod reconditioning machine. Just grinding the caps will leave the rod out of round and will result in bearing failure. If your original rods are indeed too big, they can be resized to the proper dimension by grinding the cap and the rod, then honing back to the correct size on the aforementioned Sunnen Hone.
I would like to repeat...the dimensions and straightness of the big end bore of the rods are probably one of the most critical in the entire engine.
Hope thihs helps,
