Hey guys,
So it's down to b20 or b18b? which one would be better/easier to build on boost? Let me hear what you guys think! Also is it possible to put a b16a head on a b18b bottom end to get the best of both worlds? Anyways guys let me know!
Thanks,
Jamie

either one works very well with boost.
Yes you can put a b16 head on either the b18a or b20 block.

same in terms of 'boostability' except the B20 is higher displacement, therefore higher exhaust volume, meaning turbo will spool up sooner.

ok thanks a lot guys! One more question...if I put a b16 head on a b20 would that work in my advantage? higher compression? let me know!
Thanks again for all the help guys!

yes it will be higher compression, but that doesn't necessarily mean it will benefit you if/when you go turbo. You want lower compression with turbo, to be safe.
