Interesting info on B3702 Injection timing
Unless your IJC is maxed out, start to end of injection happens while that inlet is closed, and some time before it opens to allow for vaporization, with a high overlap cam I would try advance far enough so vapor rather than raw fuel can be drawn into the exhaust.
It's theoretically possible to have the injection event after EVC, it doesn't for much duration before IVC, and only when at running temperature, not a very efficient burn
