2006 88" upgrade to 2009 96" cyclinders

I have a 2006 Ultra Classic with a 88" engine in it and i just bought a 2009 Ultra Classic with a 96" in it. I upgraded the 96" to a 103" stage 2 and I have the cylinders, pistons and cams from the upgrade. My questions is will this stuff fit my 2006 88" so i can upgrade it. Any help will be appreciated...

send those cylinders out to get bored to 95 or 98 . 95 would be cheaper because you can go with cast pistons. . send your heads out and get them ported.
turn your 88 to a 95.
