Has anyone installed a hypermax gasket and fire ring kit in their 6.0L? I Have a 2004 and have recently purchased one and in the kit that they send you they have a lapping tool for the heads and for the block. I guess you are suppose to put valve lapping compound on top of the block on the outer edge of the cylinder bore. You are suppose to put this tool in the cylinder bore and spin the tool back and forth on the lapping compound. And with the heads you are suppose the put the tool in the groove after it is machined and lap the head. I just don't understand what the hell is the point to lap the head and the block. And the rings are c-rings instead of solid steel rings. When they are installed they need to have anti-cease on them. Anyone with any info would be great!
