Even if you could do it I can't think it would be worth the bother, you can extract fairly serious power from an 8v and tbh I have never felt that the 16v is as nice an engine.
Do you have GCs latest book? If not you should get a copy it will enlighten you on lots of stuff, you are close enough to GC to call in and buy one!
Hi
Thanks for the responses, I noticed that the head was reversed after I had posted, not really what I was after. I have this crazy long term idea of doing a replica Coupe rally and whilst they were 8v originally, they mainly used 16v from what I can tell from pretty scarce info. So back to drawing board so to speak as they the original 16v head was an Abarth special as I understand it and hate to think what one would cost if you could find one.......
