When does the port close now? What was the closing point in stock trim? I have no numbers for either. I just went with Pineapple Racing's "aggressive street port" template. Some forums had good things to say about them, and no one raised any red flags when I asked a couple weeks ago. Is there a simple way to get the number off of a disassembled engine.

What is the hole in the port wall there for?
I thought it was for the primary injector. I never ran anything down through it to make sure. Kelly indicates that it would be for the EGR system. I have those capped at the top, but I'm going to check it out when I get home. I'll fill it in if it is as Kelly says (which I'm now sure that it is).
