Thanks for the pics Jeff. There's been a a few bikes with carbon buildup on the valves(
see here). Did your stock valves look anything close to the ones in the link above?
Those new valves look like they sit a lot higher. Is the piston to valve clearance adequate? Do you have to compensate at all if they are? For example, maybe a thicker head gasket?
Good luck with the rest of the build.
