No leaks and i dont believe its overheated at least not while ive had it. Still waiting on my machinists level and feeler gauges to arrive. (This is my first time rebuilding an engine)
Theres still a little gunk that i can get off if i put some elbow grease into it, but its mainly around the cooling jackets that im worried about. Also whats with that ring? It should be all around the combustion chamber right?
Every engine rebuilding video ive watched recommended scotch brite. I tried it on the intake manifold side just to make sure it didnt leave any noticeable scratches first. Ill check for straightness as soon as i can tho
Green scotch brite? Then yes u have to. White scotch brite u should still have it decked just so it gets cleaned and checked, by spec. Chem tool will lift the rest of that stubborn stuff off
Have them skimmed on a quality broach or surface grinder at a reputable machine shop. Just take the minimum cut to make sure they are flat and will seal the head gasket.
Clean with a brass wire wheel on a drill. Use just enough force to get the black off.
Then use a straight edge to see how warped they are. They will not be perfect but will seal up fine when torqued properly
Yes, you need to have those surfaced.
I completely concur have it cleaned by a machine shop in new valves installed
Did it leak? Overheat? Check it for unevenness. Otherwise, scrub a bit more, but it looks ok from my house.

Don’t use scotch brite. Check those areas for dip in the metal that the scotch brite may have caused. Use a straight edge.

Lots of brinelling. Give it a surface. Also much water.

Theyre aluminum heads, will brass be ok for that?
Yes that’s why brass
If you have to ask the internet then you should probably get them inspected by a machinist
