Welcome aboard! I dont have an ans & I just let my 5.2 mag block go so I would not be able to check & at least get a visual. FWIW I have reclocked new LA bearings & drilled a new 1/16" hole which is plenty just for basic cam lube straight up from the mains (1/8 on the ones that feed heads) & feeding heads another way is better yet as cam bearings leak alot of oil depending on the app for how critical that is. YMMV. EDIT you could call your favorite parts house & have them pick both types & holler back.
