pinto main bearings are fully grooved (360 degree), YB bearings use a plain bottom shell - the plain shell gives a higher load bearing capacity. A lot of pinto bearings are also a lower grade material.
Rod bearings are dimensionally the same, material specification differs.
Only bearings I have seen which have the plain shell are OE Ford or our own Motorsport range. Not sure about Cosworth, but if as is stated earlier they are now purchasing from ACL then they will also not be a plain bottom shell.
