Have owned 2 different 1.8s in different states of tune...
First one I had I added gti6 exhaust and intake and a decat, went well but ultimately realised it was over fuelling and this blocked the exhaust up and somehow blew the piston rings so it started drinking oil.
Next one had the manifolds and cams. This was better but the engine didn't really start to 'come on cam' until about 600rpm before the limiter, so it was largely pointless.
I think if you're going to do anything beyond the gti6 exhaust manifold and exhaust which helps it breathe, you're going to need different management. And if I was going down that route I would do as Ruan suggested and just put the already better-flowing gti6 head straight on the alloy block.

Disclaimer: The above is not to be taken to heart and is probably a joke, grow up you big girl.
