Lets me start off by saying I hate working on cars... i really really do. They are a total buzz kill Other then that I love them to death

So my problem now is I have no vacuum... I've tried the carb cleaner spay on everything and no change to the engine idle at all. The VAFC is reading positive both when at idle and at 3-4k (yeah I have a Power FC ecu, but the vafc is soldered in and zeroed out... plus the big read out on the vafc makes it easy to see the map pressure).

My question is, since the head is shaved 25 thou and I have spec b's with the cam gears at zero, could I be getting blow by that is causing positive manifold pressure?

Check your valve lash again.

 

You're going to have to adjust your cam gears to get the cams back to a true "zero" with a shaved head. As for the afc, I honestly wouldn't trust it. I have one that's pretty much just a fancy light show atm. When I was running boost, my greddy boost gauge would show 14psi and the afc would show 7. After running a datalog I found the map sensor values were correct going to the ecu (obd0 pr3 chipped with BRE), it was the afc that was the problem.

 

The approximate correction for the shaved head would only be about 1/2 a cam degree. I doubt he'd notice much if any difference. Valve lash sounds like a good place to start.
