The trouble with "touching up" cylinder heads is the flaking, just like you said. What are your options? You could have the parts bead-blasted. There are plastic beads that will strip the paint and not harm the finish of the metal. That's what I woudl recommend.
A few years ago when GM was having paint problems with their trucks and vans, recalled vehicles were beaded. Paint was easily reapplied then.
Trouble is, if you strip the metal of it's paint, you also lose some of the corrosion-resistance it has. Be sure to recoat right away.
Then again, just buy some nice chromed jugs and install them. After all, you own a Harley. You must be rich, right?
