Default sbc TBI best intake option

Currently building a 383 with Merc TBI fuel injection. Pro-Maxx 183 alum heads flow 245 cfm. 219/225 on 112 lsa cam. Looking for intake recommendations. Been told by several street engine guys the intake is a flow bottleneck by 30-40 cfm for the rest of the combo. What have others used with success?

The Edelbrock RPM AirGap intake is a good choice for your stroker.
I'm not sure what your throttle body flow rating is, but the AirGap will flow better than your factory intake..
A bigger issue is that your build will require an ECU remap and maybe injector resizing.
If you don't have familiarity with remapping, you would likely be much better off dropping an Edelbrock 650 carb on top of that AirGap intake and saving a lot of grief pouring effort into an EFI system that isn't known for its performance capability.
