RamJet intake manifold to head port matching

[Kitch]

I've just removed the 5.7 Vortec crate engine from my 93 G20 conversion van.
I'd fitted a RamJet MPFI setup onto the 5.7 and I'm going to replace the 5.7 with a BP383 Vortec replacement crate engine.

I was looking at port matching the Ramjet intake manifold the 383's alloy heads, I made a paper templates of the ports in the heads to scribe on the intake manifold face.
I thought I'd just have a quick look with an inspection camera to check the alignment, when I noticed the roof of intake runner seems to partially obstruct the cutout in the intake manifold for the injector.
I need to play around a little more, as the obstruction might not be quite that bad but regardless it will still be there.
I'll also need to put the RamJet manifold back on the 5.7 and check the same thing out.

Has anyone noticed this before?
Should I blend out this obstruction in the intake runner?
