Hi BT,
Hard to tell with the gasket, I had a big job to lever it apart, it had been put on with mountains of silicone, the same as the rocker cover, silicone everywhere. From what I could see there was no damage to the gasket between the head chamber and the push rod tunnel, but I guess the only way to find out is put a new gasket in and see if that eliminates the crank pressure.
