Default Os 25 fx max head torque problem

OS 25 FX MAX head torque problem. When I tighten the head screws down the piston gets so tight near top center I can't rotate the crankshaft. The notch in the sleeve matches the pin in the cyl. I even took the shim off the top of the sleeve and the crank shaft is littel looser but still to tight. I APPRECIATE ANY HELP WITH THIS. THANKS
