I agree with Pat (Pdiggity) to some extent, but I think head work is an important part of any turbo build up. The lower end is definitely a priority, but a valve job and/or port and polish will only help along matters. A 3 angle valve job is pretty amatuer these days...something like a 5 angle or radius valve job would work better. As for cams, none should raise or lower your compression ratio dramatically and many turbo specific grinds can really do wonders for your turbo's response time. I know Comp Cams has a good online tech dept. for cam selection if you give them your specs. It's my experience that a good head/cam selection can mean a world of difference in a turbo build. It might be a little less critical in a Honda build up, but mine was night and day.
