No physical differences in the castings for all of the SD heads, no matter the date code. I take it these are a pair you picked up along the way, not with an original SD car? (I remember you were selling SD engine/parts awhile back) It's kind of hard to tell from the pics you've posted, but if you look at the exhaust ports, you can see definite porting/grinding marks on the outer portion, deeper inside you can see the original as-cast surface which is a bit "pebbly" appearing. I wouldn't worry about there being much difference porting wise between this pair
