Default 1.8 Cylinder head

I am looking for an expert/advice on the 1.8 Cylinder head.
I have just manged to get hold of a spare head so I can get it machined and ready for a quick swap for my standard head. I want it modified for unleaded and while its here upgraded ready to run twin SU's and hopefully better exhaust, cam etc.
My engine and the replacement head are both the low compression versions and i was thinking of raising the C/R to around 9.5 to 1 and i've heard fitting slightly larger inlets helps it breath a bit better... ( from the 2ltre) but heard the stems are thinner. so probably needs new bronze guides and drill them out ?
Deck height it slightly over 88mm so have a bit to play with.
I also live close to a very good machinist who has done some great work for me in the past.
Any advice appreciated.
