Valve lash with a 528 solid.

I believe that is what MP recommends for lash, I have ran my MP solid cam at 22/24 also, no seat of the pants difference but it was a little quieter.

From what I see, MP says 28/32. That seems a bit loose to me. But I don't know much. Lol
Any benefit to running it looser during break in or does it matter?
