Even if you’ve got stock factory 4 bolt caps and bolts for free?

40+yrs ago I picked up some 4 bolt caps off a junk yard 428.
I have always planned to rebuilt the 455 from my car with those caps, but maybe they are not worth the cost of machining to fit them to the block?

I do have them in place on the bare block and I was surprised at how close to correct they look and feel. I know they have to be properly fitted, but it really is odd how close to true they seem to be.
