a lot to do with heat/255 cam.
You are correct, skim heads and thin gasket should have this thing at 10:1 with the correct calculations. Heads still have to come off, so why not do the pistons whilst they are sitting there instead of milling heads which is irreversible. You could say milling heads is cheaper I suppose but 110 10:1 pistons are like $300 I think.

The 06 and up heads already have pretty good flow, but if you want them to work them some more, sure. Just don't expect much to be gained from the cost of it though. Really just pistons or decking and a thinner gasket needed for compression. Changing all of this to, the FXDLS has the largest bore allowed for the stock cylinders and almost no one makes domed pistons for the 4.00 bore. Even if they did, you would be rolling the dice on whether they would fall in to specs to match the current bore of your cylinders. I think you should go out and try to find domed pistons that fit the 4.00 bore. If you can find them, about 6cc domes will work, but good luck. Milling and a .030 gasket is your best route, IMO.
