1800 numbers

[Oliver88pa]

Im working on an 1962 1800 dsl 283. SN 119
I have a bad head and am looking for the right number. The casting says 221 02. There should be a number between the 1 and 0 I"m told but there isn"t. I think it should be a 5 or a 9. Is there?
I"m also told there should be another set of numbers on the head. Is there?
The block numbers are 106085-AA. 221020-F. 12221.
Does all this add up to be correct and matching?
Also is this head what they call the two pc head?
Thanks

Yes it is an 1800 A series tractor and uses a 2 piece head. What is bad about your head? The other head number which is the Oliver part number will be stamped in the head most likely on the exhaust manifold side and maybe covered by the valve cover.

The head is bad for one main reason. No. 2 cyl is awfully pitted and I can see at least two cracks. One between the valves and one beside the injector hole. I assume its been letting water in over the years. I bought it not running.
So your saying the other number maybe under the valve cover gasket or beside a valve spring?
thanks
