I want to find someone who knows them well and ask about the electronics for sure on the 4HE1's.

4H is the series/family, the model (F or E) is primarily displacement only. I'd expect those engines to share most components.
Historically with Isuzu's a slightly higher letter means higher displacement. Also 1 normally means direct injection, 2 meaning indirect injection. This convention was broken with the 4BC2 engine being direct injection but that was over 20 years ago.
