Here's what I have in one of the service manuals I found online awhile ago.

This is tighter on the mains than the 5.7 which lists 0.0009-0.002 while the the HC is 0.0006-0.002. Didn't compare rod journal clearances.
It's all subject to sources I suppose. I can't imagine running a. 0005 lol.

Here's a different pdf, stating right there with 5.7 specs. They're all the same journals, which is 2.55 something.

Oh.. Something to add about the Manley crank is that it uses 2" rod journals. Chevy bearing, more or less... Narrowed with the H. Gives it better rod to block ckearance
