Car used to have a 100 shot on it, how do I know what injectors I have??

At one point my 92 had a 100 shot of nitrous on it and the injectors definately don't look stock. I don't plan on EVER having nitrous again, so now I'm wondering if these injectors will hurt performance or not.

Is there a way to tell what I have without yanking everything apart?

And question 2, does it even matter? Like if I have a chip burned for the car will it matter if these injectors are too big or not?

Right now the car only has headers/pulleys/cat-back, and I plan on going full bolt-ons. Will I have to put in different injectors? Or can I have a chip burned and leave it?

If you are going to have it tuned you probably need to know the injector size, the tuner that my buddy uses asks the injector size. What do the injectors look like? Any color, numbers or other writing on them? Post a pic if you can.

That's my next step. I'm going to snap a few pics as soon as it dries up outside. There don't seem to be any markings or numbers but I only gave them a quick once over. Have to examine more closely. Closest I've seen is this pic, I think they're the same ones as this...

Those look like LT1 injectors... there should be a rochester or lucas PN on them and possibly a logo...

If this is the case they'd be 24lb, right?
