How are you going to oil the LA heads on the magnum block?
Asking for a friend.

Up through the block. Some earlier Mag blocks have the oil passage opened already. Some need drilled.

Jabs, I am pretty sure that your .030 360 Mag block here has the holes for rocker oiling. I have had 3 here recently that did. I will look again at yours this weekend.
