So are mine, I trimmed both a low deck and high deck Hi Po Fel Pro valley pan NO BIG DEAL Easy to do with avaition snips or a die grinder Lay your intake minus the carb on the motor with the heads on it torque down and look through the intake ports and see how your manifold to head port alignment is and go from there on gasket thickness selection One of my motors likes one thin Fel Pro gasket under the valley pan and the other motors likes one both above and below the valley pan for perfect alignment Intake ports are absolutely dry now
