When the head warps there is a good chance the valves don't seat properly anymore. If the machine shop surfaced the head they should have checked this. Ask them if they vacuum checked the valves. If they checked everything properly maybe the valve adjustment is being performed incorrectly.

So what do I need to do? Do we need to get new valves?
