I'm lookin' to do a similar big-bore build (w/ L28 block & crank, & FI) and hit the same wall when trying to find a high(er) compression solution. If you're doing custom pistons, you can always make up the difference in pin-height and piston dome, like others have mentioned.
However, I'm planning on utilizing custom rods (136.6mm, or L14 rods if I can find them - not likely) and VG30E pistons. This set-up will render a perfect ±0 deck-height, a 10.7:1 CR (w/ N42 & .6mm HG), AND a higher rod/stroke ratio (1.73:1, read: less friction), AND shorter pin-height and shorter overall piston height (also read: less friction), AND Sealed Power VG30E pistons are only $20 a pop. So, it's kinda like Robello's 3.0 kit, only it's cheaper, a few more mm oversquare (shorter stroke) and 2.9L.
Also, if you remove links, you'll have to remove at least a link-and-a-half, just like a bike chain. So, that could either be exactly what you need or waaaay too much; I dunno.
