Farmall 300 casting numbers

Checking the numbers on my 300, regarding head issue as posted previously. Engine casting number
362743R2 C169, head casting 361479R1. Do these belong together. I wonder as in the past someone cut the rockershaft oiler tube off and stuck a copper tube from a fitting on the oil filter into the cut end, just shoved it under the valve cover. Found a head on line that has a second hole on the spark plug side between #2 and 3 spark plug, wondering why mine doesn't have it.
Thanks in advance. Thanks to D Slater for his information.

361479R1 is the original head number for a gasoline 300. Probably can find a date code on top between the head stud holes that are outside the valve cover.
Sounds like someone mistakenly blocked the oil passage to the rocker arms in the head gasket area. Or installed the cam bearing wrong or bearing spun in the bore and blocked the oil passage to the rocker arms.
