Either do the Hybrid with SVT heads with your 2000 block, or buy the 3.0 and drop it in. I would do this. Keep your bearings, don't mess with match porting heads.
Doesn't match porting heads require major build up of welded in metal and then porting? Lots of work, not worth it if you are not a really hard core racer. If you are hard core, and like lots of work, gor for it!
