Dropped my head off in a bucket of doom (carb cleaner of sorts) , let it sit over night, and the head came out spotless minus carbon buildup near the valve seats. Is there a magic potion to remove this buildup? I want these valves to seat perfect while I have the head off.

Thanks

Sadly, none anymore
A little elbow grease works well to clean up carbon build up. In order to seat perfect, you may consider lapping the valves

Thanks for the response. Is there a method or chemical you could suggest to aid in the process?

There are also tons of youtube video howtos for porting and polishing heads, lapping valves, etc. I recall watching one that used a dremel with a buffing wheel and jeweler's rouge.

Perfect fits require the proper tooling, aka shop tools.
Nearly perfect fits use hand tools, hand lapping and a bit of 0000 steel wool.
Bio diesel should break it down the best, especially when in conjunction with the steel wool.
Don't recommend wire brushes though.

so I used carbon off that's used for kitchen cookware. It worked better than I could of imagined! Got my head and chambers looking spotless
