China sbc head hackery

Hey guys
Weve all seen the cheap stuff on ebay, picked up a bare set that looked like they had a half way decent chamber and port to start off with...picked up some better springs, valves etc. Far from done just itching to share some goofin. Pics are as cast save for the bottom one obviously
Too much idle time. Some things need to be addressed...
Sheet is an after to see whats been done so far. Will be poured to verify but "hear" they are 198cc.....64cc chamber 2.02 1.6 valve....have some other after shots cant take a pic to save my life.

Flowed on SF600 4.125 bore 28 inches, no pipe on exhaust

Without breaking out the sheet "before" they are roughly 260/190 not bad
If you are a DIY guy pay attention to the chamber

Will get some finished pics when I can..
