Those are okay. A better choice would be a set of Isky or Crane nodulars if you can find a set that is unmolested. The Comp Cams steel rockers are also better than the Harland unbushed ones but probably more expensive. All depends on how much the guy is going to drive it. I don't think unbushed aluminum rocker arms are going to last forever on a street car, but if it is a hot rod that gets driven 1000 miles a year then they should last a long time. I've tested all of the rocker arms on TF240 heads: https://www.motortrend.com/how-to/trying-find-extra-power-rocker-arm-testing/

Another tidbit worth mentioning, there are 2 different versions of non-offset roller bearing Harland Sharps that fit conventional BB mopar heads. The -KE version is designed for Edelbrock and Trick Flow heads, the roller is moved in a little compared to the original ones. I suspect the bushed Mancini version is the older design so the tip alignment won't be the greatest and side load the valve stem some.

You can still find Crane nodulars if you look hard enough.
We found a brand new set in the box at a swap meet for $100!
I prefer them over anything with a roller on a street engine.

To use Comp ultra pro magnum rockers on BB TF heads, the two end rocker stands need to be relieved about .030” on the side that’s towards the rocker.
Obviously it’s best to do this prior to installing the heads.
