Well if you are talking about both of them being the older 63 model (not 1163) then the 63 is an offset head and the 63C is a center. I believe the offsets were used on the 510's but dont quote me on that. We have run an offset on our 750's but ran into problems with stalks getting up into the cleaning fan since the tires werent running down those rows of corn. Remedied it by welding in some steel deflectors to knock them down and keep them out of the fan. No problems then.
