no you will need bigger ones like 460cc or even 520cc to be safe with cams

You will be fine with stock injectors with drop-in cams and bolt ons

how is that? if im correct with bigger cams your valves stay open just a little longer to get more air in the cylinder so in that point you could run it richer. If you have ever looked at a fuel map from the stock ecu in ap1 or ap2 they run the same size injectors(360cc)in both car, and look at running log of the fuel injectors they spray almost the max in vtec already with stock cams. so to get the most hp out of the car you would want to problem want bigger ones.

to get the most out of cams you would want to change the time too and so to get the most hp and reliable build. i would recommend the aem 1052u standalone ecu.

Or "cheat" and get an adjustable fuel pressure regulator for $100 and continue to run stock injectors. There is always a vafc or emanage at that point to fine tune your fuel adjustments. E manage if you need timing control.

Concerning the standalone and parallel ecu our friend has a lot of choices (vafc, emanage, aem, hondata etcetc). The point here is that for sure with stock injectors he can play safely!!! If he is feeling unsafe then plug a fuel pressure regulator (as s2000Junky said) and you are more than ok!!

If the op was talking about bc cams, then YES they are drop in cams that can be used with STOCK ecu. Also i am very familiar with the ap1 ecu. Whats funny is that i dont think youre familiar with that ecu enough.
