X3 Thats all I did for a pair of Cal Customs. Plus a little red permatex over the screw heads for even more cheap insurance from having any screws back out!
I bought a set of MP`s that had some homemade baffles in them too. They have a 1/4 " hole drilled in the center of each baffle to prevent any standing oil from sitting up there i`m guessing? Probably unnecessary but it didn`t hurt.
