89 360 vs 71 360

I am about to pull the trigger on a donor truck with an 89 360. So it should have a hyd roller yes?

I have read several forums, some very recent, and still am unclear if the roller lifter motor is a better starting point than my already owned 71 360 block. The plan at this point is a solid roller 408.

Yes I understand they need to be fluxed and ultrasonic and pick the better core blah blah blah.

BUT I am asking from a price and performance stand point, is it better to start with a roller lifter block? My current understanding is the lifter bore chamfers are cut consistently and the block is cut for the link bar, thus no grinding on the block and special retrofit lifters are not required.

Please clear this up for me before I commit to this donor.
