The 24# injectors will work but will probably be at there limit NA.

If your boostn or juicing definitely run 42# or higher since u will need the added fuel to meet the fuel pressure demands of a power adder. Probably gonna be sittn on a ticking time bomb if you throw boost at a 10:1 motor and don't have a perfect air fuel ratio.

The mass air meter and TB should be matching size or close. No point in running a 80mm mass air and a 65/70 mm tb since u can only flow as much air as the smallest point in the intake system. If u keep all the sizing relatively close u will be fine. Shouldn't need more than a 70mm tb NA

24's with a 65mm-70mm tb and a 73mm+ maf that is calibrated for the injectors.

10:1 is high for boost unless you run meth or innercooler and pull lots of timing.

You will need more injector if you run juice.

30's will be fine, They held up fine on a old 347 of mine with AFR 165's, x cam, and systemax upper. I think it made 357 to the wheels. If you hav ethe funds swap the x out for a custom cam and make a ton more power.

For the Cam call Shaun at AED (916) 715-7569. Tons of people on this board go through him. Custom Cam is like $300-350. 65mm TB will be enough, but bigger wouldnt hurt.
