He is comparing apples-to-apples. The 96-103 is the "stroker" engine w/4-3/8" stroke. They call the pistons strokers from the 88" days.
To the original question- it really depends on what specific "stroker" piston you are talking about because HD markets several flavors.

To the original question- what HD generally labels as the stoker piston is flat-top the same as the kitted piston, but is forged as opposed to cast. Both flat-tops should yeild the same compression. There are other pistons though that could be termed "stroker."

You already have the appropriate piston.
You can add a domed piston for more compression, but you better know what compression your cam likes, because you can ruin the whole combo by adding too much compression!
Does your bike ride good now? Do you enjoy the ride?
Why chase numbers if you like the ride?
Unless of course you plan on painting your numbers on the side of your gas tank.

Good luck with that.

what cam you using, what pipes? that seems low for a 103? hell i have a 95 and am at 94-97 depending on weather and who dynos it... when i finished my build it dynod at 94 when we did a dyno shoot out last week it came in at 97
i have a 95 w/ flat top pistons... major dif i see is wiht forged pistons you can run a shot of NOS if you want
i can not do that with my SE flat tops as it will blow a hole in them
