Putting together my solid lifter 273, all stock parts. I have the shafts mounted with the oil holes pointing down towards the exhaust ports in the head and each shaft hole lines up with each rocker. These are cast, not stamped rockers, and I can't find assembly info in the service manual. This seems to be correct, but would like confirmation before I tighten it all down.
The notches face down. Down and to the back on the drivers side and down and to the front on passenger side. 15lbs on the shafts, anymore and you’ll distort them and I’ll be very hard to remove them if needed.
