One of the cam bushings in the block has two holes. (Can't remember if 2nd or 3rd) These holes need to be lined up with the two holes in the block to allow oil up to the rocker arms. (one is pressure from the oil gallery in the block, the other is up to the rockers) I had a machine shop install the cam bushings in my 560 and told them about the two holes. They only lined up one hole and when I fired it up, no oil to the rockers. Pulled the head, pulled the cam, took an extra long drill bit and drilled the bushing while still in place.
The oil from the cam bushing travels up a drilling in the block, then thru the head gasket hole, then thru a drilling in the head, then along side a rocker shaft bolt, and then thru the hollow rocker shaft to the rockers.
Always check for rocker arm oiling on the first fire up.
Another thing it could be is the plug in the outer most rocker shaft end brackets. If one is missing, the oil will simply run out the end of the rocker shaft.
Did you have the rocker shaft completely apart with the rockers and brackets off? If so, examine the middle brackets for one that is different. You may have it in the wrong place and oil cannot get up past the hole in the head mentioned above as it will be blocked by the bracket without the "oil" provision.
Head gasket not installed correctly and blocking the oil hole could also be the issue.
If this is a tractor that you have had for quite some time, it is doubtful that the cam bushing is indexed incorrectly. If you don't know the history, then it could be the problem.
