Now we're talkin'! But hey, it's better than welding on quarter inch thick grinding pads. Talk about making your own problem. That's a good point since I actually jack up my engine and THEN tighten down my engine mounts. Of course, IF I had warped heads, I would mill them. Every little bit helps. Good point! Especially since I never considered getting into them what I would call fun. At least not on the street. It's one thing hitting a bump or dip or getting into them because you just damn near crashed and it's another thing gettting into them because you are seriously hauling the mail. In my experience, something has GOT to give every time. I usually manage by reducing my speed but man you have got to be careful and not back out of the throttle too much or you are going to be into them more than your were to start with!
