Depends on what the rest of the build is. If this is a speed density application, the fuel pressure is going to be critical; you want to make sure it doesn't drop off under heavy throttle/open loop conditions. An adjustable fuel pressure regulator can suffice, in some cases, before aftermarket tuning is needed.

Should be no problem with the stock cam, with something else in there you'll stretch those squirters for all they're worth at higher rpms. The adjustable FPR is good insurance, though you'll need a wideband O2 sensor to know how much it needs to be adjusted.
