Not sure unless I checked but seem to remember that if your MD has been rebuilt with 4 inch pistons and sleeves the later head gasket is okay. If MD has 3 7/8 bore the early head gasket is used. IH updated heads and a lot of MD SMD heads on tractors are not original. Most heads have the casting # on left front top between valve cover and injector. Most heads will interchange. Md came with a 4 digit # on head and leter or leters following.Some SMD and later used a 6 digit # with R? following #. This from memory so don't hold me to it but think # for latest head IH sold was 277098 R?. Theres a date code on heads with a lot cast after tractors quit being sold.
