sorry to hear that. JDM bastard was gonna sell me a F22b1 head possibly along with the motor. I had the cash ready and wanted to set up a time, but since I was booked cus of my work schedule, I couldn't meet that week. Well, what do you know, suddenly he has a "buyer" and didn't inform me about the pending sale. . Sorry to say this, but you should be more careful about buying engine parts, especially pistons, valves, cams and etc.
