here is what I would like it to look like but how do I go about cleaning the circled area

 

Where did you get your head work done????

 

I would recommend using some automotive parts cleaner (safe for aluminum parts) and a stiff bristle brush. Try soaking the combustion chamber (face down in a container) in some of the parts cleaner to help loosen the carbon build up. After the letting it soak for awhile (approx. 1-2 hours), clean the combustion chamber with the stiff bristle brush and the parts cleaner.

 

Yeah, soaking is key. Just don't use anything with metal bristles or you'll scratch the hell out of the aluminim. It's a pain compared to the old iron heads. With those you could just scrape everything off with a screwdriver... And I'll take a wild stab and say that head is either a PYR or old school DPR welded head.

that look's like lips motor... and those look like ferrea valves.

 

just use a wire brush

 

Alright, you could you a wire brush on some areas but the gasket surfaces aren't going to like it if you get sloppy.
