first you need to understand that the stock head only flows about 130cfm.

Even then you'll likely find some pressure drop, and it might even go 1"hg (13.5"H2O/1/2psi) or so which will reduce peak power some, but really It's likely not to make a difference you can feel.

Now if you port the head, go with a bigger cam, and bump up the compression, You'll be increasing the flow potential and that restriction will create a bigger pressure drop and be more of a factor.

I was thinking about using a MAF, but electrically they work very different from an AFM and it was just looking to complicated. But I'm no electronic guru either.

Now I'm working on a Megasquirt. this will use a MAP sensor and eliminate any measurement device in the intake tract
