Default H22 11.5:1 compression. Injector size?

11.5:1 Compression with stock 290cc injectors? What can go wrong?

If youre building your engine you should upgrade your injectors as well. Stock injectors with stock fuel pressure duty cycle can raise too high

255 Walbro with 350cc? I'm just gathering more options before I start buying stuff again.

walbro 255 with 450cc is what you'll want. 550cc if you ever plan to use e85.
DSM bluetop 450's work great for this type of setup, but to use them you'll need to wire in a resistor box if your chassis doesn't have one.
Or just go straight for ID1050's. Then you'll have enough fueling for e85 and nitrous
