there was not much to clean up for the valves and head. i did clean up the bowls. only ported the bowls into start of the runner. it was not hard to figure out what needed to be clean up. both the intake runner and exhaust runner it self i did not touch. they look to have plenty of airflow.
factory valves are small, but they still proved to flow good power for this project build on a minibike.
before bolting the head back on . i decided to measure thickness of the new and old head gasket and they came out to be .040
i also found some info on the internet saying the gasket was .040 thick.....:thumbsup:
i wet ahead and installed the head without the gasket and found that the valve train look good. everything was lining up real good still.
so at that point i wet ahead and milled .040 off.
lots of room for bigger valves. maybe next project.....:smile:
