I had several B1/TS engines that I outfitted with spray bar oiling in the valve covers. Still had intake galling issues. My resolution ended up providing room for larger diameter, heavier walled push rods to combat flexing ( pole-vaulting ) push rod that caused impact galling.

I have to push back on your statement . All the factory blocks are drilled to oil the lifters , they were available with hydraulic lifters , so they needed this oil gallery .
