Default Should I be good with a stock fuel pump? Loaded question

I'm assuming the stock replacement should be good after reading and Ed Wright seems to be the god here and I'm thinking he's gonna say I don't need more than the stock pump.

Breakdown:
355 fully forged
LE2 heads
42lb injectors
Auto w/ 4k stall
3.73 gears
Stock fuel lines/rails

Any other info needed to help with the recommendation?

Also I have another question about head gaskets. With the heads I'm trying to figure out which gaskets to go with to get the compression up as I may be doing nitrous. I'm looking for links too if possible where to buy and part numbers of which to get. I'm sure you'll probably need more info which ill have when they get back from the machine shop being checked

What cam? I'm assuming a street grind of some sort? If so, I'd lose the large injectors in favor of some 30's. That should be plenty.

I'm no god, but if your stock pump is good, that's all you need. 30lb injectors are more than enough.

Stock one should be fine NA. Wouldn't a higher-volume pump be a good cheap insurance policy if running nitrous though?

And I concur with 30s being plenty of injector.

Not if it says Walbro on it. LOL
When the new pump weighs about half the original, there is a reason. Plastic is light.

The cam is an LE spec'd cam 236/244 .608/.608 110 LSA. I'll keep the 42lbers just in case I go bigger. What brand and size injectors? Like actually 30lbs or 32,36?

And also what are you N/A guys running for head gaskets to keep the compression up?

And Ed you may not be a god but you are definitely a great mentor on here and I try to keep up with your advice

What up Jay?

I had my stock pump with 30lb injectors with that very setup and spray on it. Ran well and never had issues.

Stock pump with a fuel pump booster wire harness kit.

Hey rob. You got another stock pump? I f*cked up the other one you gave me trying to swap it only to realize it was fine and didn't need replacing. Im also now looking for some 30lb injectors too
