changing the oil wont hurt anyway, since its een a part , then you can have a look at it.
Im wondering if the rocker area could be worn causing more oil to escape qaround the rocker shaft bushings. maybe that coudl contribute if there is a drainback issue.
I know little about how the ford 300 arrangement is but in my older volvo I found wear there. I put the rocker shaft on my lathe, it is too hard to turn but I have a toolpost grinder so I reduced the shaft size by about ..010" one end was .001" thicker. ,by grinding not cutting. then polished it.
and then I just had new bushigns made. I had them made to fit snugly on the smaller end, then I used brassso to work them in so each had a nice sliding fit and enough room for oil. I went a little further and faced off the sides of the pillow blocks and rocker surfaces and then made bronze washers for them to run against. originally it was cast against cast. but those surfaces had wear too.
It worked.
a new rocker shaft is hard to find for that engine so that was my rather low budget workaround.
