Nowt wrong with the Sti 6 heads,nice little port and polish job will give good results.
As for the block - not a CDB as stated above unless its already had a rebuild and fitted with a EJ207 twin breather,semi closed deck block.
Decent set of ARP(or similar) head studs will give better clamping of the head gasket to the block.
The STi V6 heads have a staggered bolt pattern for the Inlet Manifold whereas your WRX will have an Inline bolt pattern - so another potential problem when you come to fit it.

i think im told that i have got a cdb in mine at the moment because it has cross hatch markings by the crank pick up
as for the heads from what your saying i would need a inlet manifold from a version 6.. is that right??

Yep - you need a Vers.6 inlet manifold to go with the STi 6 heads - the engine wiring loom connectors are different and the ISCV is different also.
You might be better off selling the STi 6 engine and putting the money from that towards building a good Forged engine with your CDB.
If your not ready to pull your engine yet,you can pick up a good standard CDB(bare block) from the likes of API for about 200 notes,and build it up from that.
Just my opinion though.

to be honest ur probably right.. i broke down on sat at scooby shoot out because the return pipe come off the bottom of the turbo an had to get the rac to bring me home..
i was hoping it had`nt done any damage to the engine but i have found out today it has because i can hear a nock so its f*c*ed...
luckly i have another scooby breaking with a good engine in it so im goin have to use that, didnt want to realy as i could have done with selling it... never mind at least iv got my cdb now to rebuild..
wot heads would you say are best then for my engine ??
