Big bore
Cheaper, and better, to just get a crate engine. Though, I did a 95” with Andrews tw26 cams, and it ripped! I think I ended up with 88hp/105tq

88 and 96 jugs are the same, it's the stroke that changes to make it a 96.
95 and 103 jugs are the same, it's the stroke that makes it a 103.
103 and 95 pistons are different though, wrist pin location. So you can use your 103/95 jugs with 95 pistons only on your 88 to turn it into a 95, 103 pistons won't work unless you change the stroke.
Your only option is to use your 103/95 jugs and buy a set of 95 pistons BUT if your buying a set of pistons you can always buy 98 pistons, have your 88 bored to 98 and sell your 103 jugs and pistons to offset the cost
Hope this all makes sense

The heads are the same as what you have now, but 06 and up castings flow better. So better heads, especially with a .030 head gasket.

If I opt for boring my 88 to 98 should I use the heads that came with the 103? I should add that they are SE heads if that makes a difference

Those heads will fit on all Twin Cams, but some years require a manifold change (newer to older/ older to newer swap) Stock 06+ castings, flow better, and seeing how yours are Screaming Eagle, even better yet.
You could build a pretty strong 98"
We have a lot of experienced engine builders on the Forum. Someone will be along soon with a lot more knowledge. Good Luck

Cost is relative, in my world I find it pricey BUT if you were going to go for the longer stroke then I would highly recommend getting a trued and welded crank.

If you want it to be a 103, you need a 4.375 stroke flywheel set made for 99-06 TCA engines, so it's compatible with your drive train.
Expense is parts + fluids + tuner and time, easily a couple grand at a minimum- much more if you're paying someone to do the work. Most places charge between 10-15 hours to replace flywheels, so with the cost of new flywheels, you could easily spend $4k
