Which heads on 1994 magnum block

The speed pro h116cp standard bore. Thought about the kb107 but heard that they had some skirt issues, and the speed pro are close to being stock weight.
What is the issues with the skirt issues? I haven't heard anything about them. I bought the short block off my friend that built it. He was switching to a gen3 hemi. But any way the KB107 have seen a bunch of 6500/7000 rpm shifts and a few 7500. Lol also I thought the KB were soposed to be close to stock Weight. Unless I was told wrong..
