Help me identify an injector

I can get a set of injectors fairly reasonable but am having trouble identifying them.
The #'s on them are F7PU-A4A and 9F593 and they are black top.

That is a link I found. I was told they were 36 lb ford injectors but I'm not certain.

With the stock LSx fuel pressure of 58lbs, they should max out around 41-42lbs of fuel. This should make for a 500whp build. My car made 493whp with SVO 30lb injectors.

Use this page to give you a rough estimate of fuel needs.

Remember, this is assuming the car is tuned properly.
