Junkyard 5.9L Magnum + Edelbrock LA heads build

Are you going to drill holes in between the holes on your oil filter adapter plate?
I'd do it on a 4 hole plate but would pause on the Magnum 6 hole plate.

Don't think I have ever seen a set of rod bearings so uniformly worn with the copper showing the same on all 8. Would make me wonder if the rods are distorting when the nuts are torqued.
