The 257 shortblocks are probably the easiest and most accesable way to go. The 2.2t closed deck are tanks, i can't say if they are interference or not.
Are your heads still good? a hybrid would probably be a good option 257 block with 205 heads, but i have heard of them having oil breather problems, that was on my friends track only car, but he was running lots of boost on a big turbo.
Do you think you could possibly bore then sleeve your existing block? probably not, but that would be the cheapest option and give you a very strong platform, maybe even get a little more displacement.
What turbo are you running I can't remember...all the damn drugs aahaha
