I would figure that it wouldn't be any more expensive to get a S2 or 968 motor compele and just swap them. Sell your 2.7 and the S head (these go for decent money)

I was not putting down the 16v head but I have also seen 400+hp 951 cars with the 8v head so it can deal with a decent amount of flow. I know that is forced but it speaks well of the heads ability to flow air.
