There are two places that align bore here in town. I think you need to cut the thrust area radially for the later style bearing with the 440 source caps.
As far as needing them or not....it's a hotrod. I have three building of impractical cars and parts that I could have substituted with cheaper versions. People have been using studs and aluminum caps with success for a long time.
If this package warrants the AL caps make it happen.
