Identifying INternational T9 Dozer models

A Friend has a International T9 Petrol start Diesel dozer.
Has cracked head being repaired, has had several repairs before.
Engineer repairing head wants to know which model T9 it is. He informed us that there are several different T9 models and that international increased HP through these changed models.Does anyone know how we can identify what model we have.
Number one sleeve is protruding about 1/32 above the block. We will try to press it back down. If it cannot be moved, can we leave it as is.
Are ,n normal replacement head gaskets available, I mean Not solid copper one's.
Thank's on advance :roll:
 
you are saying its gas start diesel so that maks it a TD9. T9 is the gas model. the diesel model has the 335 cid engine. then the cid was
increased to 350 cid . look at the serial # and that will give you your information . or post serial #. in 1953 they had a bore increase to
3.5" which is the 350 cid. as for the sleeves they must all have the same protrusion. plus it will be very hard finding any parts and
gaskets. you basically need to start searching for wrecked tractors with that engine for parts. wd9 or super wd9.
 
The liner should press back down and have the right protrusion above the block when it is home,you can try Olsen gaskets for the gaskets you need at the link below.
