Dave Hopkins is the KTM head rebuild guru. He also goes by DJH on KTMTALK. He is in Wash state, rebuilds and fixes heads with 1mm larger valves and does it right. I would send it to him if he can get it done in time. If not then do it yourself. How many hours on the motor? May not need anything else. Head is easy, the rest is much more work, but still not hard, just more.
