I have a 1974 AQ130 it had a cracked head when purchased. Bought a head out of Tx. and had it worked. Put it all back together with new gaskets& torqued by the book specifications but I am still getting water in the oil. Any help finding where the water is coming from.

 

could be a cracked block

 

Can be the water pump, has a seal if the seal is bad water go through
