Have you though of using a 7afe head, its narrower and can also make 200hp easily.
The ports are better angled as its a later, lighter head and the only issue is the block
with its pissy rods and less bolts for the flywheel.
Billzilla.com has a turbo 7afe that he prefers over his 4age. He says with 4 people
in the car you cant notice the difference with the extra cc.
The only issue is the dizzie I think but a 150usd megajolt kit is all you need to rid
the dizzie and have windows 95 and on programmable igntion via laptop or netbook.
