the main difference is the vvt, the block has two lugs to block off the oilways   so you can fit a non vvt head to a vvt block, but trying to fit a vvt head to a non vvt block might have issues

  so shouldent be a issue using my crank and head in a A20nft (gen 3 block ) from a astra vxr which should equal up to 400 + hp   and my next question will my pistons and rods be ok ( will i need new rings head bolts gaskets etc etc ) and is it worth opening out my exhaust ports while im there to match the exhaust primarys ??  

  Careful, you sound perilously close to installing a full turbo engine (and joining the dark side!).  

You can pick up a brand new A20NFT of eBay for about £2.2k (maybe slightly cheaper if you shop around), almost complete. You need another couple of £k at least to get it running however..
