So if I mount the engine upright it won't be visible over the top of the cowel, I would just need the hole for the plug clip to enter or should I cut a opening for the whole head. I did get some aluminum motor mounts adn a new cowel so I can put the engine in any placement at this point. The top of the cowel looks nicer without any visible openings but a hole for the plug clip might not be too bad looking.
