Default Bore scoping intake port

Hey guys,
My issue I'm having or think I'm having, is that my car is slow. Like really slow.
It's got an MS4 cam and supposedly ported factory heads.
Made 370 at the tire. The heads are 853's. The car is an 01 (didn't 01 and 2 get 241s). It has an ls6 intake.

I want to verify the heads are ported.
What I'm trying to do is snake cam the intake runner of the head through the injector port on the intake. Can this be done? And do I have to pop the whole rail off, or can I get one injector out.

I found a couple bore Scopes. Thier diameter is 9mm or 11/32"
What is the injector bore size on the intake.
Can't for the life of me find it.

Thought about that. But then I think I remember reading that there was a step or a throat in the bung that the end of the injectors kinda rest on, which is smaller then the injector body OD

How many HP do you think you are short? A port job on those heads won't make too huge a difference between being done or not.

Not really sure, but I guess that's the point.
One of those things that I'm trying to check off before this winter, so I have more of game plan.
