In reading this post does this make sence my head is 3836848. My block is 3769716. When i had the engine rebuilt i had a short block that was ordered and the shop rebuilt my head. My truck is a 54. Gmc canadian model 9300. When i installed the moter it had no oil going up to the riockers. The guy at the shop went to the back and came back with a small tube that went from the block to the head under the side cover after that it was all good so my question is what year of block or head did they need the tube. The casting numbers if read right show 58 to 62. Seems odd that i need the tube for oil. Opps the truck moter is a 235 and from the headcasting number that was on the truck appears tbe head was not origional as it is newer than 54
