Fueling & Injection - 42 lb injectors too big?

I have an ls1 will have MTI stage 2r heads at 62cc (being shipped),has a 232/230 .580/.580 110 cam, and will have a 90/90 setup on it. Also plan on spraying a 150 wet shot. I have some FAST 36lbs which are actually 42ish at our rail pressure. Just wondering if this is going to be way too much injector for the car? Thanks.

You should be fine with that setup with a proper tune, they are a little large, but it gives you room in the future.

Nope, not at all. I've got 42's on my car and drivability is great. Just be sure to use a good tuner. Most use Nic D. here in Az
