Next, cams and ported heads.

Yup! Those #s pretty much track mine, up to the point where the heads were also ported. At that point the Fidanza FW was also installed, netting 432 rwhp.

In the future (late this winter??) I'd like to tweak the porting (TB) and the exhaust, AND add cams; the goal being 455-460 rwhp at that point.

Stay tuned!

Paul, hoping for the same when the heads get done.
