leaking cylinder l134 head

[c90001]

I have problems to get the cylinder head tightly and have noticed that are the cylinder liners come 0.02 inches out. The head I had grind from a garag and extra made a copper gasket., after about 200 km it was defective. I guess I had the valves of the cylinders 3 and 4 set incorrectly. After I had also changed the breaker cam, I could adjust the ignition accurately. But whenever the car was hot started the motor to stutter and had no more power. In the last trip in got one problem more,the engine had a bearing failure or a valve Beat. When the starter turn the engine Without a cylinder head one notices anything.. I'll let grind the engine block and the camp will all check. What am just confused is that the cylinder liners come 0,02inch out. That's maybe normal?
