Painting an engine on a highly detailed build is the foundation for everything else, spend a few extra dollars and do it right and the other details are simple bolt ons. Go the cheap/fast route and have an issue or change your mind later to up the accuracy level you are shooting for and it's a MAJOR PIA to strip it all down and start over. I'm doing this exact thing for one of my customers right now, he decided to bring his car to a higher standard part way through his build and his current engine paint color/gloss level is way off.

So,
short cutting with a fresh engine build just doesn't make any sense IMO
