302 head progress and questions

Cool I got my gaskets and a paint pen so I’ll work on that.

Assuming the valves are fine, would I be wrong to not have a valve job done when they’re checked over?

Look forward to part 3. Will it have the exhaust ports? I don’t want to get into water lol.

Yes.
Again, try and get the window opened to the port runner shape, its oval and smaller in the pics. Work the guide, don't leave its length humped in the middle when you finish. Leave it ramped like the turn, mimic the floor somewhat, narrow it. Get it to half of it's as cast size and out of the way. Shorten the guide too, 3/8 at the hole, leave the material beyond the valve guide hole on the bowl and profile that to a peak that quickly blends to the bowl. Move the straight wall over some..make the bowl the largest area and not the entire half of the runner leading to it.. push back on the top of the short turn at the straight side aka common wall.... make it look like the other side but slightly higher...and shoot for opening the bowl to 85% and it will make really good power. That's assuming all the chamber work is done...which is no.1
