head

umm i am almost positive that you can't but it would just be better to put a b6 sohc in you can get either a 16v or a 8v the 16v is a little better than the 8v with more power and more towards the high end vs the 8v with power in the low end and the power drops off pretty quick. The b6 bolts right in with very few modifications and you should get the b6 ecu it would have better fuel maps.

not entirely positive it would work, but even if it did physically fit, it wouldn't make any more power without more compression and tuning, for the effort and price you're better off with the whole engine, which can be had for less than $400 on ebay and i'm sure quite a bit less in the junkyards.
